Today we first discussed Homework 1 and Homework 2. We then looked at how downsampling a signal changes the Fourier transform. More specifically, we looked at the relationship between the Fourier transform of a sampling x[n] and the Fourier transform of a downsample of this sampling y[n]=x[Dn], where D is a positive integer.
