卷积算法的DSP实现，程序中的例子是正弦波卷积冲击信号和正弦波卷积方波的仿真-Convolution algorithm of the DSP implementation, examples of the program is a sine wave signal and a sine shock convolution convolution square wave simulation

1)设计一个IIR低通滤波器，用它去处理一个30kHz的方波信号，得到1kHz干净的正弦波信号，设采样频率为30kHz 2）用直接二型实现结构、二阶级联实现结构和并联实现结构去进行滤波 3）在滤波的时候，假设输入、滤波器系数和滤波结果均被量化，保留小数点后两位-A) Design of a low-pass IIR filter, it is to deal with a 30kHz square wave signal to obtain a clean 1kHz sine wave
