Corrections: At 3:52, I say "If you choose a small frequency resolution", when I meant to say "If you choose a small time resolution". The point is that choosing a small(large) time window makes it easy(hard) to resolve small changes in the time domain, but makes it hard(easy) to resolve small changes in the frequency domain. At 7:06, I say "... that matches our previous understanding of self-phase modulation", when I meant to say "... that matches our previous understanding of self-steepening". It is self-steepening that causes the peak of the pulse to slow down, thus making the back slope steeper and generating a large blue chirp.
Awsome...I didn't notice this video in your channel. I remember, i asked you about spectrogram before my thesis defense. Thanks a lot for making such informative videos.

I love these videos. They really help with understanding of why these processes occur for math Luddites like myself!
As an electronics Luddite, I quite appreciate your videos as well! :-)

@@naymulhasan8559 You're welcome! Hope your defense went well!
Great video
Thank you!
