Description
So that's what we're gonna do today, we're going down more the second path, including an extremely important operation. So we're gonna have three big items today, each of which are important in themselves and come up all the time. One is delays, what to do with a Fourier transform when the signal is delayed. One, a formula for what happens to the Fourier transform under a stretch, and finally, a very general operation, which we have now seen a couple times in different forms, but today we're gonna see them today in the context of the Fourier transform in its full glory, so to speak, and that is convolution. ...
