摘要: A circuit is disclosed for sampling analog signals at a rate which is a rational, non-integer fraction of a clock frequency. The analog signal is sampled at non-equidistant sampling points, with the distances between successive points forming a jitter sequence. The jitter sequence is pre-calculated and stored in a memory within the circuit, reducing processing requirements in use.
