A computer program for designing self-equalized equiripple, even order filters is presented. The program permits its operator to attempt to meet a given set of filter response specifications by positioning either the imaginary axis zeros (i.e., the insertion loss poles) or the complex plane zeros (i.e., the equalization poles) of S/sub 21/(s), or both. Once the zeros are optimally located, the program will first synthesize a symmetric canonical, cross-coupled array filter from the two-port, short-circuit Y-parameters. Next, the program will convert this structure, by a series of plane rotations of the coupling matrix, into an assymmetric canonical configuration. Both calculated and measured response data are presented.
