Description

This is a Mathematica notebook that investigates frequency-domain properties of the Rectangular, Hanning, and Hamming windows. It also illustrates some different kinds of plots possible in Mathematica. It is instructive to explore the effect of changing the various parameters such as window length M, FFT size NN, and the "alpha" parameter of the generalized Hamming window.
