This program for the Timex-Sinclair 1000 computer was written for completely automated design of Butterworth low-pass, high-pass, band-pass or band-stop filters. Modern solid-state transmitters are more prone to harmonic and parasitic frequency radiation, and therefore it is desirable for the radio amateur to have access to modern filter design in order to comply with present
