  • Review by Miguel Castellanos

You are clear about your thought process in both proving the periodicity property and computing a DTFT. This can be helpful because those general concepts can be applied to other similar problems. I also like your use of color to indicate the what term in the expression your are talking about. In your second computation, remeber that the DTFT is a continous function and therefore you must use the continous delta function, which is infinity (not 1) at a single point. Good job overall!

I enjoy the flow of this Slecture and the use of color to highlight the use of certain variables in equations. I also enjoy that the Slecture is short and sweet which makes it easy read and process. If there was one caveat I comment on it would be that in the last line that the DTFT of the complex exponential is repeated every 2*pi. Other than that is a great lecture, good job!
