The Fourier Transform and its Applications
This is an exceptional course. In my CS undergrad days, some 7 years ago, when I wanted to make sense of Fourier Series and Transform, this course was my savior. The mathematics text book had a dry and unintuitive treatment of the topics and electrical engineering, physics and computer science books mostly relegated the topics to a few pages in an appendix.<p>I found this course and printed out the PDF of the lecture notes as I didn&#x27;t have enough bandwidth for watching the videos. The lecture notes had a wealth of information about the idea of a Fourier Series expansion, it&#x27;s connection to the Transform and the applications in diverse fields.<p>Prof. Osgood had great examples. In one such example he showed that the temperature of a ring must be a periodic function of time as the structure of the ring is periodic in space, and then went on to derive an equation for the temperature of the ring that was a Fourier Series.<p>It was from these notes that I learned a great deal about convolution too. The new website looks much better organized. I&#x27;d recommend every CS&#x2F;EE student to at least watch the first few lectures once.
