# hohmann2002_freqz - Frequency response of hohmann2002 filter or filterbank

## Usage

h = hohmann2002_freqz(filter, z)
H = hohmann2002_freqz(fb, z)


## Input parameters

 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)

## Output parameters

 h The complex frequency response at z. Each column represents a response of a filter.

## Description

Description:

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.
