摘要：
Sampling rate conversion finds greatly useful in the area of multirate signal processing, communication system, speech processing system, etc. In this paper, we describe a structure of 72 MHz/54 MHz sampling rate conversion system which is applied to HDTV system. First, we discuss the theoretical model of a 4/3 conversion scheme and then design the hardware structure implemented in parallel and illustrate the sub-system structure in detail. Finally, the phase diagrams are presented to show the relations between the clocks.
