I am in need of a bandpass filter that is asymmetric about DC on complex samples. That is, I would like a true complex bandpass filter that has pass-band of positive frequencies without a pass-band mirrored in negative frequencies. I suspected that iirfilt_cccf would design such a filter but it does not appear to. Am I doing something wrong or is such a filter available otherwise in liquid-dsp? Thanks!
