说明：  生物医学信号处理是以数字信号处理为基础的离散信号及 离散系统的研究，因此．其预算过程基本上都是卷积或者相关预 算。在MATLAB中可以很容易实现这种运算。
(Biomedical signal processing is based on digital signal processing discrete signals and discrete systems research, therefore. The budget process is basically the convolution or related budget. In MATLAB, can easily achieve this operation.)
