h = hohmann2002_freqz(filter, z) H = hohmann2002_freqz(fb, z)
|filter||A filter created by hohmann2002_filter.|
|fb||A filterbank created by hohmann2002.|
|z||A vector of frequencies in z-plane for which the frequency response will be computed. z = exp(2i pi f/fs)|
|h||The complex frequency response at z. Each column represents a response of a filter.|
h = hohmann2002_freqz(filter, z) returns the frequency response of filter created by hohmann2002_filter.
h = hohmann2002_freqz(fb, z) returns the frequency responses of the individual filters in the filterbank fb created by hohmann2002. The responses of the individual filters are stored in columns of h.
