Monday November 7, 2011 (Week 12) - See Course Outline.
Today we presented the linear filtering interpretation of the short time Fourier transform. We also obtained a formula for reconstructing a signal from its short time Fourier transform. We then moved on to the topic of "Spectral Analysis of 2D Signals" with an introduction to some basic "space" signals.
