Abstract
A new approach to designing polyphase filters with all-pass sections in the individual branches is presented, which is based on a certain number of attenuation zeros in the passband. During the optimization procedure of the overall attenuation characteristic, only the frequencies of these attenuation zeros occur as independent variables, therefore, the problem of directly optimizing the large number of filter coefficients is avoided.
