Abstract
A digital decimation filter system for oversampled A/D (analog-to-digital) converters is addressed. To achieve very low passband ripples for data acquisition converters, a cascade of a comb filter and some bireciprocal equiripple wave digital decimation filters is applied. The complexity of the filters is minimized by taking into account the noise shaping of the modulator. An example is considered, involving the design of a digital decimation filter for a 16-bit sigma-delta A/D converter.Keywords
