LowPassFilter

代码说明：

说明：  内部含3个模块，使用DDS产生200k与500k的正弦波，两者相加后过数字低通滤波（通带0-200k，阻带400k以上），并将波形输出，实测FFT分析中看不到500k分量。其中数字滤波器采用MATLAB设计（FIR+等波纹，阻带衰减-80dB）(There are three modules in the system. DDS is used to generate 200K and 500K sine waves. After adding the two modules, the digital low-pass filter (passband 0-200k, stopband above 400k) is used, and the waveform is output. 500K component can not be seen in the actual FFT analysis. The digital filter is designed by MATLAB (FIR + equal ripple, stopband attenuation - 80dB))
