Abstract
A delta modulation-like sampled analog filter structure for realizing low-pass filters is described. The filter uses only the coefficients 
, and 
and can be fabricated as a programmable CCD filter. Interpolation and decimation are employed to increase the accuracy of the delta modulation. It is shown that with this scheme a given response can be realized arbitrarily closely. Examples are included.
