they do a lot better than chebys of the same order, but it's quite
impossible to recalculate their coefficients at runtime. if that is
demanded, the polyphase design probably wins easily.
Tim, do you have any more info about this filter design procedure? I've
currently got a nasty filter design problem that I'm looking for a
solution for.
