WFILTINFO - Plots filters info

Usage

wfiltinfo(w);

Input parameters

w Basic wavelet filterbank.

Description

wfiltinfo(w) plots impulse responses, frequency responses and approximation of the scaling and of the wavelet function(s) associated with the wavelet filters defined by w in a single figure. Format of w is the same as in fwt.

Optionally it is possible to define scaling of the y axis of the frequency seponses. Supported are:

'db','lin'
dB or linear scale respectivelly. By deault a dB scale is used.

Examples:

Details of the 'syn:spline8:8' wavelet filters (see wfilt_spline):

wfiltinfo('syn:spline8:8');

Details of the 'ana:spline8:8' wavelet filters:

wfiltinfo('ana:spline8:8');
