iirgroup
group delay Lp IIR filter optimization
Calling Sequence
[lt,grad]=iirgroup(p,r,theta,omega,wt,td) [cout,grad,ind]=iirlp(x,ind,p,[flag],lambda,omega,ad,wa,td,wt)
Arguments
- r
vector of the module of the poles and the zeros of the filters
- theta
vector of the argument of the poles and the zeros of the filters
- omega
frequencies where the filter specifications are given
- wt
weighting function for and the group delay
- td
desired group delay
- lt, grad
criterium and gradient values
Description
optimization of IIR filters for the Lp criterium for the the group delay. (Rabiner & Gold pp270-273).
