ABSTRACT:
A method of modulating the sampling period of a sampled system with a factor N, and correcting the data stream of the sampling system with the same factor N, thus minimizing distortion artifacts induced by sample frequency modulation. At least a one-period delay from receipt of a new data stream value is used to avoid heterodyning with the incoming stream.
