基于MATLAB的FIR数字低通滤波器的实现设计-The realization of the FIR digital low-pass filter based on MATLAB design

采用一种基于FPGA的IIR数字滤波器的设计方案,通过QuartusⅡ的设计平台，采用自顶向下的模块化设计思想将整个IIR数字滤波器分为：时序控制、延时、补码乘加和累加四个功能模块。分别对各模块采用VHDL进行描述后，进行了仿真和综合。-IIR digital filter using a FPGA-based design, analyzes the theory and design method of IIR digital filter, then through QuartusⅡ de
