Minimumphase filters with Matlab?
Posted:
Jul 14, 1997 5:22 PM


What I am doing is implementing methods to obtain minimumphase filters instead of using what polystab.m do. Some of my methods have as output the zeros (FIR) and poles (IIR) of the desired minimumphase filter, hence what I need is to obtain the impulse response of the filter from these zeros/poles, I can use poly.m, but it doesnt work well for high orders. I tried to split the total zeros into sets such than the poly.m function works well to obtain every impulse response of every set, then the total impulse response is the convoution of every impulse response set and I used the conv.m function and found the same problem as the use of only poly.m. I'd appreciate if you someone has any idea how to solve my problem.
