ABSTRACT:
A data interpolating filter is disclosed, in which a wave digital filter is used for processing two-channel data with one data path. A sample and hold part samples and holds data, and selectively provides the sampled and held data for at least two different channels. An adapter filters the sampled and held data from the sample and hold part to produce interpolated data. The adapter filters the sampled and held data using a selectable one of at least two different filter coefficients, and a filtering signal delaying part delays the interpolated data in response to selecting signals.
