A decimation and interpolation filter design

基于ORCAD 的无源RC POLYPHASE 滤波器设计资料，包含有1阶，2阶，3阶滤波器的设计。可以直接打开进行仿真分析-ORCAD passive RC POLYPHASE based filter design information, including a first-order, second order, third-order filter design. You can directly open simulation analysis

利用电流传送器CCII实现的有源polyphase滤波器设计，ORCAD软件仿真的，可以直接打开，运行-Use of current conveyor CCII achieve active polyphase filter design, ORCAD software simulation, you can directly open and run

此程序是用vhdl语言编写的多相滤波器。使用了ip核。并且配有测试程序，是正确的。-This program is a polyphase filter vhdl language. Use the ip core. And with a test program, is correct.
