In the fourth lecture, we finished computing the Fourier transform of a rep, and we computed the Fourier transform of a comb. We then began the second topic: "Spectral representation of DT signals". After giving the formulas for the DTFT and the inverse DTFT, we observed the periodicity property of the DTFT and computed the DTFT of a complex exponential.
Action items:
- Finish the first homework. It is due Friday (in class).
