ABSTRACT:
A sample rate converter is formed by a cascade configuration of a partial filter (20,22,32,26,28) and an equalizer (26,28,30,34) for equalizing the frequency characteristic of the partial filter. For obtaining a minimum-complexity equalizer when the complexity of the partial filter is minimized, the equalizer is arranged as a feedback system including in the feedback path an equalization filter that is substantially equal to the partial filter.
