@4:03 you see a guy getting confused and prof sees that, then clarifies that he'll ralk about it in a min. Great lesson

Thank you MIT for your unselfish act of sharing knowledges and info from top calibre professors.

I just thanks MIT for this gift !

Lecture are very fantastic, amazing !!!

Rolling the phase on Fourier is genius.

1. As argument of sine goes towards zero, the limit is the argument. 11:15

after watching these videos i realize how dumb my teachers are and how brilliant mit's faculty is

my jaw dropped so far down you can only see it with that signal processed witchcraft of a microscope

Sir, when we look at the instantaneous freq of an AM signal it is Wc, in FM we get Wc+msg*k,but when we take the Fourier transform of those schemes,we get some result, but not matching intuitions 🤔

What did he mean by the audio signal is insensitive to DC. min: 5:50.

did he explain BPSK in that lecture series ??

The messige h,h great teacher

Outrageous! Is Dennis Freeman really presenting this microscopy technique as the 'idea' of him and his PhD students? This was developed in the 90s, and is now well known and widely used. It is known as Structured Illumination Microscopy and not 'Phase-Modulated Microscopy'. For example, see Enhancement of axial resolution in fluorescence microscopy by standing-wave excitation, 1993. Laterally modulated excitation microscopy: improvement of resolution by using a diffraction grating, 1999. Surpassing the lateral resolution limit by a factor of two using structured illumination microscopy, 2000.
