Today we began by reviewing the the relationship between the CTFT of a signal x(t) and the DTFT of a sampling y[n]=x(nT). Then we moved on to the topic of sampling rate conversion. After introducing two operators (upsampler and downsampler) we looked at how changing the sampling period affects the DTFT of the sampling.
