STFT, Triangular Window, 50% Overlap

This case is essentially the no-overlap rectangular-window case with the window-length doubled and the window-transform squared, as derived in Chapter 3. The squaring doubles the channel isolation in dB. To move the folding frequency out to the first zero-crossing, 75% overlap should be used ($ 4\times$ oversampling in time).
