NettetThe instfreq function computes and displays the instantaneous frequency in one step. instfreq (y,fs, 'Method', 'hilbert') The method fails when the signal is not monocomponent. Generate a sum of two sinusoids of frequencies 60 Hz and 90 Hz, sampled at 1023 Hz for two seconds. Compute and plot the spectrogram.
