The difference between CTFT and DTFT is clearly stated and the derivation for DTFT sampling at frequency above Nyquist rate is concise. It would be better if you provide more steps when computing DTFT sampling at frequency below Nyquist rate.

I really liked the use of matlab plots to illustrate the DTFT sampling below and above the Nyquist rate. However I wish there was more steps in the actual calculations of these curves as I found it a bit hard to follow in that aspect. Other than that I find it a great slecture with the matlab content really aiding understanding a lot.

Great job with the graphs! The matlab plot show the signal and where it is being sampled at was a great illustration. The calculations for the frequency domain needs to be more detailed. Also you don't seem to indicate the magnitude scaling from the two different sampling rates.

Great job! All the important points within the topic are emphasized and stated clearly. The graphs are good visuals as well. In the sampling above Nyquist section, the third line of the derivation has a small typo. Within the second delta, the 2000 isn't completely factored out. All in all this was a great slecture.
