This is me Vikas kumar jha(Jumbo). I had made a playlist for the Fast Fourier Transform (HERE)https://www.youtube.com/playlist?list=PLiINLbWPTveq8TuXDjsISg7fPHCrTO0oy).
Here, I made a playlist of five video, where First(https://www.youtube.com/watch?v=zJNtUVBg-tc&list=PLiINLbWPTveq8TuXDjsISg7fPHCrTO0oy&index=1) video is on basic overview of F.F.T. Second(https://www.youtube.com/watch?v=M-fZWdbL4UA&list=PLiINLbWPTveq8TuXDjsISg7fPHCrTO0oy&index=2) video is on explanation of D.F.T. Third(https://www.youtube.com/watch?v=XFxc7LCB0PE&list=PLiINLbWPTveq8TuXDjsISg7fPHCrTO0oy&index=3) video is on dry run an example of D.F.T. Fourth(https://www.youtube.com/watch?v=hrYJwBPha4w&list=PLiINLbWPTveq8TuXDjsISg7fPHCrTO0oy&index=4) video is on explanation of Inverse F.F.T. Fifth(https://www.youtube.com/watch?v=ER7EtbhNBXg&list=PLiINLbWPTveq8TuXDjsISg7fPHCrTO0oy&index=5) video is on dry run an example of Inverse F.F.T.
If you like my teaching method, then you can suggest me more topics which you feel hard. I will try to make cakewalk for you.
Feedbacks are most welcome. Thanks for reading.
