A General Method and FORTRAN Program for the Design of Recursive Digital Filters

Abstract

A general method for the design of digital filters is presented, and a FORTRAN program that follows the steps of the method is described. The computer program can design any low-pass, high-pass, bandpass, or band-reject digital filter by using either Butterworth, Chebyshev, or elliptic approximations to the ideal rectangular type frequency response. The user need only provide the program with a set of structured specifications, and as output the user obtains the transfer function of the minimum order filter that meets his requirements. For convenience, the transfer function is expressed in a form that allows immediate implementation in a cascade type realization.
