** I really liked your slecture. Showing how <math>e^{-j2{\pi}n} = 1</math> was really helpful. Also showing the common mistake students make in continuous time was useful. You really showed the necessity for the guess and check method in this derivation. Overall this was a great slecture that was easy to follow and understand. | ** I really liked your slecture.

| − | + | Your slecture was really good. I liked how you showed how the wrong approach to solving the problem with the exponential would only lead to trouble. I also liked how you explained the periodicity property and added the fact about the exponential equaling 1. It could be a good refresher for someone reviewing the topic. | |

There is a lot of good work but some of the data seems extra such as e^− j2πn = 1 which can be said is true only when n is an integer and not any real number. In the example it would be good to mention the sifting property for the integral of a delta. I like how the reasoning is explained for the work and why the idft is used unlike the dft.

Really great explanation. I like how you showed the common mistake that student make with continuous signals. The slecture could be improved with some graphical examples. I disagree and think showing e^− j2πn = 1 is helpful. It will always be true in this case since we are working in discrete time. If you didn't realize this the simplification of the sum could be confusing.
