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.
