Today we continued talking about sampling. This time, we focused on the relationship between a discrete-time represesentattion of a sampling $ x_d[n]=x(nT) $ and the original signal x(t). We noted that, in the Fourier domain, the signals differ in three ways (repetition, amplitude, scale).
There was a short quiz at the beginning of the lecture. This was the second quiz of the semester, and of course it was just for practice.
Action Items
- Begin working on the fifth homework. It's due Friday.
- Begin preparing for the first test:
- Review the difference between CTFT and DTFT.
- study the sampling of pure frequencies (e.g., HW2) and make sur you understand how this fits into the general pattern of sampling which we covered today.
