Programmable CTD filtering using coefficients 0, +1, and −1
M. R. Bateman, B. Liu · IEE Proceedings G (Electronic Circuits and Systems) · 1981
In a previous paper, a simple filtering scheme based on delta modulation and using only coefficients 0, +1, and −1 was presented. In the present paper, those results are extended to highpass and bandpass filters and various techniques are presented to improve the performance of these filters. Examples are provided.
