Abstract:

A set of digital recursive filters has been programmed on a digital computer. The filters are low-pass and band-pass realization of Butterworth and Bessel characteristics. The method of synthesis, which is described, is by means of the matched z-transform of correcponding analogue filters. Some examples of time and frequency responses of the filters are presented.
