The work is very concise and easy to follow. In the introduction it might help to put a mathematical explanation of Nyquist, which is mentioned in the second section. Also color would help to distinguish the different sections of the plot and how when T is too small the parts seen between <span class="texhtml"> − ''p''''i''</span> and <span class="texhtml">''p''''i''</span> comes from repetitions and not the initial transform k = 0.

Questions and Comments for DTFT of a Cosine Signal Sampled Above and Below the Nyquist Frequency

A slecture by ECE student Andrew Pawling

  • Review by Jacob Holtman

The work is very concise and easy to follow. In the introduction it might help to put a mathematical explanation of Nyquist, which is mentioned in the second section. Also color would help to distinguish the different sections of the plot and how when T is too small the parts seen between p'iand pi comes from repetitions and not the initial transform k = 0.


  • Review by Fabian Faes

The overall flow of the slecture is very easy to follow and understand. I thought the graphs and the accompanying explanations were very easy to follow and understand without too much difficulty. from my point of view I cannot think of something for improvement since I find the mathematics easy to understand and clearly explained. Great Job!


  • Review by Botao Chen

Good job! Your demonstrations are easy to follow and your outlines are very clear. Is is a good reviewing material for me because of your use of graph which strongly support the demonstration. I could clear see what is going on when the Nyquist rule is violated and when it is not.

You clearly explained that if CT signal is sampled above  Nyquist rate , there is no aliasing.  And if it is below Nyquist rate there is aliasing.
