Design of multi-channel digital signal multiplexer/ demultiplexer based on FPGA

基于FPGA的多路数字信号复分接器的设计

In digital demultiplexer, when the number of frequency bands is equal to decimation ratio, the structure of polyphase filter is efficient and easy to be realized. However, its application scenario is limited.

在数字分路中，当抽取倍数等于频带数目时，多相滤波器结构高效且易于实现，但是应用范围有限。
