Abstract
A method and apparatus for converting sample rates of digital signals includes processing that begins by receiving an input data stream at a first sample rate. The processing continues by retrieving predetermined integrated samples at the first sampling rate, where the predetermined integrated samples are derived based on a ratio between the first sampling rate and a second sampling rate. The processing then continues by adjusting the retrieved predetermined integrated samples based on data values of the input data stream to produce adjusted integrated samples. The processing continues by differentiating the adjusted integrated samples to produce an output data stream at an output sample rate, wherein the second sample rate is a multiple of the output sample rate.
