I cant explain how amazing you explain Not boring Not so fast Not So slow you speak with the language which student can understand in one word you are amazing bro Greetings From Iraq
I'm sure that this channel becomes one of the best channel for electronic students in youtube .Superb is just a word for your explanation. Thanks a lot for your help.
I came across this video to learn a different topic but I stayed and watched because for once I think i finally understand what the heck a Fourier series is and all the concepts around it.. thank you so much !!!
You are the best teacher ever.... I was struggling to learn the signal course and I have watched, neso academy, Gate plus, and many more but I could understand why I am studying this!. what is this thing. Watching your video, my all confusion is gone now. thank you for your help. Now you are one of the best teachers in my life.
Hello Iman! i'm learning DSP from your course. firstly i'm alot of thanks to you for your great course. please can you explain in 19:56 , why you replace K by P for what purpose? i hope you reply for me
what an amazing man woooooow iman I just loved being an electrical engineer because of you man thanks a lot it is beyond science it is real pleasure!!!!!!!!!! thanks man!
Thanks a lot for your positive feedback. I didn't forget to apply the boundary. Please note that the integral is just non-zero at t=0. So, you just need to replace t by zero in the integral. Hope this helps.
So far the best demonstration of Signals and Systems in You Tube. Excellent presentation of concepts that make learning fun. The pictures in between also add to the videos in setting a bright mood in the course of the videos. Thanks for such a great work! Will there be DSP lectures too sometimes in future?
Hi Anindya! Thanks for your amazing feedback and support. DSP is my next course for sure. The creation process is currently very time-consuming and I am working on a platform to speed it up (Castofly). I will create a lot of tutorials on DSP in the future!
I dont understand something in 9:26 you use formula with the sine and in 13:46 you use the formula with the cosine but if i use the same formula with the sine there i get another answer not the same so how can i know where to use each of them? and why do i get there another answer?
24:42 c(-k)* = c(k), and c(k)= - c(-k) at right above. So c(-k)* = - c(-k). Then I think c(-k) is j or -j something cuz j* = -j. The signal is imagine, isn't it ?
crystal clear so its 1+ punch of zeros and man thanks alot for your tutorial im learning alot (this is my second time playing this list ) hope ill do will in my exam
thank you very much Iman for your great explanation , but I was wandering about : should Ck = C*k and not C*-k for it to be real ,,why are we putting conjugate for - k
So? Fourier series is a time-domain to frequency domain transformation method for periodic signals? Or is it just a representation method for periodic signals?
It's too clear. It solved a problem that had been bothering me for a long time. I only have a question for the second example. It seems that you chose [-3, 3] to be the period and this integration only has sense at t=0 due to unit impulse, and the exponent goes to 1. However, I chose the period as [1, 7]. the sensing point are changed to t=6, and in this case the exponent cannot be 1. What am I thinking wrong or how do I solve this problem? Thank you very much.
This world needs more teachers like you!
Thanks a lot, David.
I cant explain how amazing you explain
Not boring
Not so fast
Not So slow
you speak with the language which student can understand in one word you are amazing bro
Greetings From Iraq
Hey my friend. I can't explain how amazing you are :) Thank you for the kind words!
@@Kuchdelan What software are you using! Your tone is just perfect and easier to understand! Thanks a lot!
You are a living legend sir! Thank you for explaining the topic.
You are most welcome

Thanks for your kind words and pleasure to help!
Thanks a lot. You just saved my Mid-Sems.
Glad I could help!

thank you for your help.
Now you are one of the best teachers in my life.
You are very kind Abdul. Thank you for your feedback and it was a pleasure to help you understand the topic.
@@Kuchdelan Please make new videos. I am waiting for your videos.
Hello Iman! i'm learning DSP from your course. firstly i'm alot of thanks to you for your great course.
please can you explain in 19:56 , why you replace K by P for what purpose? i hope you reply for me
These videos are straight value. Short and really helpful. You're training the next gen of engineers sir
Thank you! You are very kind 🤗
I did not get the idea when I was studying EE long time back in college, through your video, I finally get it. Thank you very much.
Thank your very much for your feedback. It is a great pleasure to help you understand the concept.
Thanks a ton for making my day !! I have learnt more than my college teacher who never explained in subtle way
Thank you for your kind words and support. It is such a great pleasure to help!
you are the best teacher!
Glad you think so!
You are a great teacher, thanks a lot
You are welcome!
You are an amazing teacher, Thank you so much for all the effort you put in creating this great content!
You are an amazing student :) Thanks Lyna!
Somethings not clear: how are you so good at this?! Well done bro!
Lollll. I am not sure what's wrong with me ;)
Thanks Iman!! I have learnt a lot from your signal processing tutorials. Now, I can relate this to control system with deep understanding.
Thank you very much my friend.
best video , great teacher, God bless you and your family
Thanks a bunch! You are the best ;)
You teach mesmerizing well, Iman! Good job!
Thank a lot, Ahmad!
what an amazing man woooooow iman I just loved being an electrical engineer because of you man thanks a lot it is beyond science it is real pleasure!!!!!!!!!! thanks man!
Thanks a lot for your kindness and amazing feedback. It made me really happy. Cheers!
you are excellent teacher !
thank you so much for the amazing tutorial. one thing to mention is that at 12:00 c_k = 1 ,you forgot to apply the integral boundary.
Thanks a lot for your positive feedback. I didn't forget to apply the boundary. Please note that the integral is just non-zero at t=0. So, you just need to replace t by zero in the integral. Hope this helps.
Omg i thought the same😂

@@Kuchdelan Done! :-D
very very good lecture
thank you ;)
Iman thank you very much!
You are welcome
It was very useful. thanks for your lecture.
you are very welcome! thanks for watching ;)
I dont understand something in 9:26 you use formula with the sine and in 13:46 you use the formula with the cosine but if i use the same formula with the sine there i get another answer not the same so how can i know where to use each of them?
and why do i get there another answer?
I think I missed it. What was the meaning of ck? Around the 10 minute mark.
Thanks a ton for the videos and greetings from Sweden
Hey Lars. Thank you for your feedback. CKs are the weights for different frequencies. Hope this helps.
not what i was looking for maybe after the exam will check it ^_^
At 10:00 When k=0, c_k is indeterminate, and L’Hopital gives 1/2
That's correct.
damet garm mashti ;)
mamnon Sherwin jan :)
Can you please make video on Convolution
I do have a video on convolution:
th-cam.com/video/Y-h7qoTVQtw/w-d-xo.html
th-cam.com/video/LIs0h34iFN8/w-d-xo.html
Are there any
lectures on IIR and FIR filters
How r u getting the period in the frequency domain
do you also have videos on electromagnetic course ?
Sorry Mahsa, I don't :/ best of luck with the electromagnetic course!
At 15:07..the area is negative..how is an area -ve in physical world?
Please read this post:
math.stackexchange.com/questions/2360208/can-an-area-have-negative-portions
This is not the physical world. However, an analogy in the physical world can be made
quick question.. why so awesome?
Loll! Not sure what's wrong with me ;)
Thank you so much! Helped me a lot! ^_^
pleasure to help. cheers!
24:42 c(-k)* = c(k), and c(k)= - c(-k) at right above. So c(-k)* = - c(-k). Then I think c(-k) is j or -j something cuz j* = -j. The signal is imagine, isn't it ?
Your explanation is good, but can you explain how sir Fourier has arrived at the Fourier synthesis and Fourier analysis equations
Lol! I guess he was just a genius ;)
@12:00 isnt that the integral of e^0 is one and replacing with the period ull get 1/6*(3+3) so the answer is one ?
Please note that delta(t) is not one across the whole integral. The only non-zero location for delta(t) is at the origin. Hope this helps.
crystal clear
so its 1+ punch of zeros
and man thanks alot for your tutorial im learning alot (this is my second time playing this list ) hope ill do will in my exam
Thank you very much & good luck.
At 14:48, should W0 be pi/3?
T is 2, so w0 is 2*pi/T = 2*pi/2 = pi
thank you very much Iman for your great explanation , but I was wandering about : should Ck = C*k and not C*-k for it to be real ,,why are we putting conjugate for - k
Hey Boshbosh, thank you very much for your comment. I proved the property at the end. Please let me know if it is not clear.
@@Kuchdelan my apology ,,I got it ,,you right,,,تشكر اخي
@@boshboshish no worries at all ;)
4:13 - Not definitely LTI or definitely not LTI? There is a difference in the meaning.
The system is not LTI as the frequency has been changed.
So? Fourier series is a time-domain to frequency domain transformation method for periodic signals? Or is it just a representation method for periodic signals?
Yep, former is true.
you are great , thank you :D
Mohamed Atef thanks a lot, my friend.

Thank u
thankx dude!
For Phone thanks a lot for following my tutorials ;)
GREAT
thanks!
TY
mr iman pls how do I relate. this time domain Fourier transform stuff to medical image processing
Isnt yellow = blue + green?
No, yellow is red + green ;)
