if you go to a decent university you study all the maths and logics that gives you the physical and mathematical MEANING of this plot. this is just a practical procedure
Prof Wage, I just want you to know that with your clear, simple explanation, you taught me in 20 minutes what my PHD professor and his PHD student assistant could not in several hours of convoluted explanation. I'm sure I'm just one of thousands of students whom you have helped with this lecture. You are the living embodiment of the difference between a teacher and an expert. Thank you.
THANK YOU SO MUCH!! oh my god, my lecturer spent 5 hours talking about the same thing yet I couldnt understand, while i understood everything after watching this clip.
Hello, I am a student at the University of Evansville in Indiana. Thank you so much for the video. This is the only video I have found out there that explains this concept in a very easy to understand way. You are a great teacher. Thank you.
Thank you a lot. I am in my 2nd bachelor's and now studying for "analoque systems" and our professor cannot explain this easily. You did a great job letting me understand this.
Mam, I thank you from the bottom of my heart, this video has so beautifully explained to me how to easily do bode plots by hand. I have an exam tomorrow and this was the perfect revision video to go through!
Wow this is exactly what I am looking for. My professor didn't teach us anything besides basic cases for Bode plots for 3 LECTURES!!! And aside from that expected us to derive transfer functions from those without any examples. It is professors like you that really save engineering students' lives. Keep up the good work :) P.S.: Sorry if you have Lipo
I need a video like this but for the phase. Both solving for initial phase and for the phase response for all frequencies. This one was great though, glad that there are professors who share such valuable knowledge online.
Thank you for sharing this. I am a student from CSU Long Beach and really needed this for review. Please consider networking with professors at other schools to share lecture videos as backup for when students struggle. I would have loved to have my prof tell me this is a good review rather than have to search through so many videos myself.
too bad indeed, but she did say that this was only going to demonstrate how to generate the bode magnitude plot. i'm sure there are more videos that show how to do the phase plots as well.
Great explanation I have a engineering professor that has 9 patents and his first job was at NASA and he can not explain this to save our life. However there is no such thing as 0 DB
thanks a lot your awesome really i had my brain overheat trying to study it by myself. I really appreciate it hope for more electrical engineering subjects and thanks again :D
at 7:31 how to draw 20 dB/dec slope for 's' passing through 1 on 0 dB. I mean at what angle should it be drawn. from which dB point. you started it from somewhere between -20 and -40. how to know that point from where it should be started
i might be ocd about this but i cant stop staring at the red line and purple line not touching -40(red) and -80(purple) they should be touching cause thats what 20dB per decade means:) Great video btw pretty good if you're trying to remember what you once knew.
There is one point that I don't get. In the first example when you are going to add the redline with the blue line that starts from -40 dB you are starting from -80 dB , why?
consider the three lines intersecting the y axis at 0 dB, -40 dB and -40dB. If you want the intersection point of the combined lines, then 0+(-40)+(-40) = -80. Now, this combined line (representing the bode magnitude plot) has only one slope +20dB/dec, due to the zero (s term) of the system. So it slopes up to 1000 (which is the corner/breakaway frequency of the first order system). The corner frequency is where the Bode plot's slope changes suddenly changes, it's inversely proportional to the time constant of the system [a bit of extra info] .
it's 20 db/ decade , a decade starts at 0.1 ---->1 , but the lg w (horizontal line ) is "delayed" at the start with 3 sqares on the paper , that's why on | H(jw) | line is down 3 square , to maintain the 20 db curve. maybe it's personal preference on drawing , but w should be in lg scale , here it's linear scale
I am a ordiniarus of root locus and bode etc. There are many much truth about it and some times shits happen. I didn't send any prophet about Feed-back control cause I am the GOD of FEED_BACK_CONTROL
can any one please answer me for something like (s) to be sketched at what value does it cross the vertical line " goes to zero frequency" it make sense to me to be (minus infinity) but it is totally wrong and i don't know the reason can any one help me
9 years later and this is still a FABULOUS explanation of the topic. thanks a ton for the clear, concise, well organized explanations :)
in 20 min you explained what my professor could not do in 2 lectures, Thanks!!
literally!
Our professor explained this in few minutes expecting us already understood. Thank you so much !!!!!
That's why I don't go to lectures
Cos' you were using your phone instead of paying attention
fak yu, harry esmode the best
so im supposed to be at a top university and im literally learning everything off youtube.
Thanks a lot for this
Well, that's a professor's explanation
Same here, I'm paying University of Colorado and Learning from TH-cam and communicating over Zoom, seems like a ripoff to me..
loool I'm in exactly the same boat as you bro. Top uni but learning everything off yt
if you go to a decent university you study all the maths and logics that gives you the physical and mathematical MEANING of this plot. this is just a practical procedure

I'm sure I'm just one of thousands of students whom you have helped with this lecture. You are the living embodiment of the difference between a teacher and an expert. Thank you.
So far this is the best explanation of bode plots on TH-cam
Introducing the four common terms as background before drawing lines was really helpful thank you
my lord - very good - very clear - very short lecture explaining every thing - thank u my lord =amarjit = india
THANK YOU SO MUCH!! oh my god, my lecturer spent 5 hours talking about the same thing yet I couldnt understand, while i understood everything after watching this clip.

Dammnnnn!!!!! I am trying to understand from two weeks. Your 16 minute video was enough for me.....
you are the best one who explained it in allover you tube videos and google articles , thank you from Egypt
You literally saved my grade. Not even the class supplemental videos helped as much as this!!!!
Straight to the point. Perfectly and very simply explained. Thank you so much for your help!!!!
Thank you a lot. I am in my 2nd bachelor's and now studying for "analoque systems" and our professor cannot explain this easily. You did a great job letting me understand this.

THANK YOU!! my professor cant even explain this in two hours
Best explanation i have seen. Thank you for sharing!
Best explanation I ever see ! Thank you very much
Thanks ! So easy ! I looked for a lot of videos, and they were all awful. This is a real explanation.
Perfect, thank you ma'am. Now I will look for someone who can explain the phase plot as clearly as you have done here. Cheers!
I thought thats a sir the entire time until i read this what is wrong with me
Thank you for sharing this. I am a student from CSU Long Beach and really needed this for review. Please consider networking with professors at other schools to share lecture videos as backup for when students struggle.

I struggled quite badly with this topic, but this video made everything clear for me. Thnx!
Great video, always good to watch it again to refresh my mind!
Thank you. Your tutorials are very easy to understand.
This was so well done, so much better than my college prof. About to go ace this quiz that I formerly wasn't prepared for!
THANK YOU !! Female ECE professor !! very rare. YAAAY!!!
thank you so much, so much better than my prof, life saver, saved my as*. Big shoutout, thank you!!!!
Looks like I might not fail my test tomorrow after all. You’re a blessing)
Thanks a lot. You are my best professor.
thank you for saving my final exam
This explanation is so clear. Thanks a million
Very good recording. Too bad it does not show the drawing of the phase diagram. :(
too bad indeed, but she did say that this was only going to demonstrate how to generate the bode magnitude plot. i'm sure there are more videos that show how to do the phase plots as well.
most of the time she is doing OPPS!!!
Subscribed within 5 minutes. Thank you.
You are appreciated Professor!! Thank you so much
thanks a bunch mam !! you r easily one of the best
Thanks!!! You've saved my life so quickly!
Thank you ordinarius professor, god bless you!
thanks alot prof. saved my life
Great Job Professor Wage! It would be great if you could do the same thing for the phase plot.
Great explanation I have a engineering professor that has 9 patents and his first job was at NASA and he can not explain this to save our life. However there is no such thing as 0 DB
It is a great explanation of the magnitude part, but we needed the phase one too.
Thank you so much for explaining Bode plots!
This is a very good video, but where is the part about Phase plots? This is only ½ of the subject!
Extremely helpful and easy to follow! thank you so much!
Very clear explanation, thank you!!
nice video, clearier than my lecture slides XD
Thanks so much for nice and easy explanation.
thanks a lot your awesome really i had my brain overheat trying to study it by myself. I really appreciate it hope for more electrical engineering subjects and thanks again :D
Thanks for your good explanation it's very helpful
Thank you very much, tomorrow is my mid exam, hopefully it goes well!
This is the best, thank you SO much!
Great job, very nicely done!!
You deserve a wow!
at 7:31 how to draw 20 dB/dec slope for 's' passing through 1 on 0 dB. I mean at what angle should it be drawn. from which dB point. you started it from somewhere between -20 and -40. how to know that point from where it should be started
excelent video. very gold explained. thank you very much
That was explained what took my professor to do in 4 lectures
Thank you very much, very helpful for my exams
so Bode Spotted here :) Thank u, good explanation
Wonderfull🎉
i might be ocd about this but i cant stop staring at the red line and purple line not touching -40(red) and -80(purple) they should be touching cause thats what 20dB per decade means:) Great video btw pretty good if you're trying to remember what you once knew.
Very clear explanation. Thank you.
There is one point that I don't get. In the first example when you are going to add the redline with the blue line that starts from -40 dB you are starting from -80 dB , why?
Very clear and helpful, thanks a lot
satisfying explanation
all appreciation
thank you. It really helps me.
Thank you. This made so much sense.
why final slope starts from -80????
consider the three lines intersecting the y axis at 0 dB, -40 dB and -40dB. If you want the intersection point of the combined lines, then 0+(-40)+(-40) = -80. Now, this combined line (representing the bode magnitude plot) has only one slope +20dB/dec, due to the zero (s term) of the system. So it slopes up to 1000 (which is the corner/breakaway frequency of the first order system). The corner frequency is where the Bode plot's slope changes suddenly changes, it's inversely proportional to the time constant of the system [a bit of extra info]
.
add the red line and the blue line
You sound like Blue the bird from the animated movie "Rio".
Nice video btw.👍
You are the best!!!!!!!!!
Very good! Thank you teacher!
I don't get why you sum the three different functions to get the overall response, since in the expression of H(s) they are multiplied and not summed
When you take 20log on both sides, the terms on the RHS will be subtracted and added respectively.
Question : is 1+(s/1000) = -20log|1+(jw/b) because it's in the denominator of the transfer function ?
You are amazing, please explain phase too.
Amazing explanation, thanks so much
thank so much! this lecture is very useful.
7:08 should your line be at the 20logk starting mark?
it's 20 db/ decade , a decade starts at 0.1 ---->1 , but the lg w (horizontal line ) is "delayed" at the start with 3 sqares on the paper , that's why on | H(jw) | line is down 3 square , to maintain the 20 db curve. maybe it's personal preference on drawing , but w should be in lg scale , here it's linear scale
Thank you so much. I finally understand this stuff now.
thank you so much mrs Wage
Amazing video! Thank you so much :)
thanks you very much. really helpful for my understanding
I am a ordiniarus of root locus and bode etc. There are many much truth about it and some times shits happen.
I didn't send any prophet about Feed-back control cause I am the GOD of FEED_BACK_CONTROL
And if we have, let's say h[n]={0, 1, 1, 6, 0, 1}, how do I sketch this?
Thank you a lot!! Great explanation.
You're so good!!!
Could you make one about phase plots?
What if you had a constant in the numerator as s^2 would it be a constant slope of 40 dB?
What about the Phase plot? Is the phase plot just the gain?
Thanks for the informative video!
You save my life.
great video. thank you
Wanna one more video on phase plot please ♥️
i guess frequency plot always starts from 0.1 or 1 not 0
coz we cant explain zero in the decade system
Best explanation
well done amazing video super if I give you some uni examples would explain
can any one please answer me
for something like (s) to be sketched
at what value does it cross the vertical line " goes to zero frequency"
it make sense to me to be (minus infinity) but it is totally wrong and i don't know the reason
can any one help me
Best one out there
Thank you professor
Why does the plus 20 db/dec start at -40 & not -20 because that would mean it increases by 40 db/dec not 20
