摘　　要：为了实现DSP技术与滤波器技术实验教学的有机结合,以一块万能板为底板,把以TMS320VC5416为核心的CPU数据处理电路、以TLV320AIC23为核心的CODEC语音采集与编解码电路、电源电路以及其他接口等电路优化组合,制作了数字滤波器实物,并通过CCS设计平台,编写了经典FIR滤波器程序,进行软硬件调试,完成了基于DSP的数字滤波器实验模块实物的设计、制作、安装、调试和实验过程。In order to achieve the organic combination of DSP technology and filtering technique for experimental teach- ing, a digital filter which used a universal board as its backplane was designed in this paper. It optimized combined the hardware circuits such as data processing circuit which used TMS320VC5416 as its core, sound collecting and coding cir- cuit which used TLV320AIC23 as its core, power supply circuit and other interface circuits. The classic FIR filtering procedures were programmed through the integrated developing platform CCS. After debugging the software and hard- ware ,the design,assembling,debugging and experimentation of the experiment module were achieved completedly.
