The main procedure of the experiment was to sample a signal with different sampling frequencies and observe the differences between them. This experiment is important for us because it aims to teach how to use matlab commands to reconstruct a sampled

多速率数字信号处理，它的时域和频域特性，级联等效，用MATLAB实现采样率转换器-Multirate digital signal processing, its time domain and frequency domain characteristics, cascade equivalent, using MATLAB to realize the sample rate converter
