I’ve just put together some review notes on the discrete Fourier transform and filters. In part this was to correct a couple of notational inconsistencies between my lecture and the textbook. These are related to the definition of the Fourier coefficients, which disagreed from the text by a scale factor of N.

Please take a look at both the written notes, which you can find here: signals.pdf, and the accompanying video, which is linked to the notes, which you can find here:YouTube.

See you all Thursday!
