DEMO_FRAMEMUL Time-frequency localization by a Gabor multiplier This script creates several different time-frequency symbols and demonstrate their effect on a random, real input signal. Figure 1: Cut a circle in the TF-plane This figure shows the symbol (top plot, only the positive frequencies are displayed), the input random signal (bottom) and the output signal (middle). Figure 2: Keep low frequencies (low-pass) This figure shows the symbol (top plot, only the positive frequencies are displayed), the input random signal (bottom) and the output signal (middle). Figure 3: Keep middle frequencies (band-pass) This figure shows the symbol (top plot, only the positive frequencies are displayed), the input random signal (bottom) and the output signal (middle).
