Very clear explanation of Nyquist Theorem in words, which is also supported with graphs. Also,I need to mention exception that you provided. I am not sure if signal can have such FT.

  • Review by Fabian Faes

I enjoyed the mathematical steps that were taken to show how the Nyquist Theorem upholds when performing reconstruction, however I do believe that more graphs would have been beneficial in the understanding. The fact that there is a strong conclusion which states how reconstruction is sometimes possible even though the Nyquist condition is not met is an important message to be closed on. Overall it is a good slecture!

  • Review by Michael Hayashi

I enjoyed the presentation of the Nyquist Theorem in this slecture. Your proof was solid and the coloration of the center copy removed the need to have more graphs. It was a fun exercise to include the Nyquist-violating sampling example in your presentation; nothing could have done a better job explaining the sufficient, but not necessary, aspect of using the Nyquist condition for reconstruction. I applaud the thoroughness and accuracy of this slecture.

  • Review by Chloe Kauffman

This was a very helpful slecture for Nyquist. I would have liked to seen the tie between sampling at exactly above Nyquist, versus even larger of a sampling frequency for real world design application. I.e. sampling at just above Nyquist requires a nearly perfect LPF with sharp cutoff, vs. limitation of even larger Nyquist rates. Your graphs and explanations aided in the topic learning.

This slecture was very clear and very well detailed. The inclusion of diagrams made it very easy to follow.
