Chao Chen, Wei Zhang Xu, Lu Si · Applied Mechanics and Materials · 2013
This paper first reviews the polyphase filter in the decimation and interpolation application, and simply introduces the multi-rate system. And then through the simulation experiments, the characteristics of the sub-filter of the polyphase filter were analyzed. Finally, according to the characteristics of the sub-filter, this paper presents an application in multipath delay.
