ABSTRACT:
A sample rate converter includes a first interpolator which generates samples intermediate samples provided at a first sample rate. A second interpolator, using the intermediate samples, generates further samples at a second sample rate which are intermediate the intermediate samples. An accumulator which accumulates a value representing the ratio of the first and second sample rates, generates scale factors for performing the interpolations, and a clock signal at the second sample rate.
