LowPassFilter
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))
