Up to the present time, there has existed no general method for obtaining the pole locations of minimum-phase constant time delay filters of desired selectivity. Since constant time delay filters are necessary for low distortion FM transmission, and minimum-phase filters are easy to construct and align, a general method for locating the poles of minimum-phase constant time delay filters would be of considerable importance. Presented in this paper is a procedure for locating the poles of minimum-phase constant time delay filters of desired selectivity, using a FORTRAN digital computer program. Two experimental FM receivers were built to test. the new filter characteristic, and the performance of these receivers is discussed.
