[outsig, mfc] = modfilterbank(insig,fs,fc);
insig | Input signal(s) |
fs | Sampling rate in Hz, |
fc | Center frequencies of the input signals |
outsig | Modulation filtered signals |
mfc | Center frequencies of the modulation filters. |
modfilterbank(insig,fs,fc) applies a modulation filterbank to the input signals insig which are sampled with a frequency of fs Hz. Each column in insig is assumed to be bandpass filtered with a center frequency stored in fc.
By default, the modulation filters will have center frequencies
