DEMO_GABMULAPPR Approximate a slowly time variant system by a Gabor multiplier This script construct a slowly time variant system and performs the best approximation by a Gabor multiplier with specified parameters (a and L see below). Then it shows the action of the slowly time variant system (A) as well as of the best approximation of (A) by a Gabor multiplier (B) on a sinusoids and an exponential sweep. Figure 1: Spectrogram of signals The figure shows the spectogram of the output of the two systems applied on a sinusoid (left) and an exponential sweep.
