com.oregondsp.signalProcessing.filter.iir.ThiranAllpass
public class ThiranAllpass
Designs and implements Thiran allpass filters. Thiran allpass filters are used to interpolate signals by a fractional sample. They have unit amplitude response, thus have no amplitude distortion, and approximate a flat group delay equal to the indicated delay D. The group delay function is maximally flat at 0 Hz.
