数字信号课程设计，FIR的低通带通高通和IIR的低通带通高通滤波器的设计源程序以及主程序-Digital Signal curriculum design, FIR low-pass band-pass IIR high-pass and low-pass band-pass high-pass filter design, as well as the main program source code

使用DSP和MATLAB设计的一个低通FIR滤波器,基本上实现了滤波的效果-The use of DSP and MATLAB to design a low pass FIR filter, basically realized the filtering effect

能够生成几种代表信号并且进行频谱分析、功率谱密度分析，还含有一个iir低通滤波器和一个fir高通滤波器的简易示范(It can generate several representative signals and carry out spectrum analysis and power spectral density analysis. It also contains a simple demonstration of IIR low-pass filter and a fir high
