    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!!

      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.

    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!

  • @purplerayquaza866
    @purplerayquaza866 6 ปีที่แล้ว +10

    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

  • @0451Deus
    @0451Deus ปีที่แล้ว +1

    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.

    • @dabulls1g
      @dabulls1g 6 ปีที่แล้ว +6

      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.

    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

    @jjay11a 8 ปีที่แล้ว

    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.

  • @hakanozkan8036
    @hakanozkan8036 4 ปีที่แล้ว

    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?

  • @muhammadfaizan9729
    @muhammadfaizan9729 7 ปีที่แล้ว +7

    why final slope starts from -80????

    • @shaikhsumitnoor9759
      @shaikhsumitnoor9759 4 ปีที่แล้ว

      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]
      .

    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

    7:08 should your line be at the 20logk starting mark?

    • @luciang9547
      @luciang9547 7 ปีที่แล้ว

      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

    Why does the plus 20 db/dec start at -40 & not -20 because that would mean it increases by 40 db/dec not 20
