说明：  这片是写的数据信号处理可查那个设计的报告,报告包括卷积演示程序,演示采样定理,模拟滤波器设计演示—从模拟低通滤波器到模拟高
(This is a written report on data signal processing that looks up the design. The report includes a convolution demo program, a demo sampling theorem, an analog filter design demonstration-from analogue low pass filter to analog high)
