DTWFBBOUNDS - Frame bounds of DTWFB

Usage

fcond=dtwfbbounds(dualwt,L);
[A,B]=dtwfbbounds(dualwt,L);
[...]=dtwfbbounds(dualwt);

Description

dtwfbbounds(dualwt,L) calculates the ratio \(B/A\) of the frame bounds of the dual-tree filterbank specified by dualwt for a system of length L. The ratio is a measure of the stability of the system.

dtwfbbounds(dualwt) does the same thing, but L is the next compatible length bigger than the longest filter in the identical filterbank.

[A,B]=dtwfbbounds(...) returns the lower and upper frame bounds explicitly.

See dtwfb for explanation of parameter dualwt.
