Group delay of filter cascade


D = groupDelay(H,N)
[D,F] = groupDelay(H,N)


D = groupDelay(H,N) returns a vector of group delays, D, evaluated at N frequency points equally spaced around the upper half of the unit circle. If you don't specify N, it defaults to 8192.

[D,F] = groupDelay(H,N) returns a vector of frequencies, F, at which the group delay has been computed.
