I like the fact that you have used specific numbers for the example part. By doing so, it was actually very easy to understand. However, I wish there were a little bit more explanation of how the equations progress.

Questions and Comments for

DTFT of a Cosine Sampled Above and Below the Nyquist Rate

A slecture by ECE student Sahil Sanghani



Please post your reviews, comments, and questions below.



  • Review by Yijun Han

The derivations are clear and concise. When sampling at a sample frequency below the Nyquist rate, the reason why aliasing occurs is well explained. But there is a typo on the second figure. The frequency of the last delta should be 2pi*330/550 instead of 2pi*770/550.
