Abstract
A sample rate converter includes a filter for processing digital data in response to a clock controlled by a clock enable signal, the filter receiving the digital data at a first sampling rate and outputting digital data at a second sampling rate. Resampler circuitry generates first selected periods of the clock enable signal having a first duty cycle approximating a ratio between the first sampling rate and the second sampling rate. Selectively, selected periods of the clock enable signal are generated having a second duty cycle for minimizing an error accumulated over the first selected periods of the clock enable signal.
