代码说明:

  生成一个采样频率2000,由50Hz、120Hz、200Hz正弦信号以及噪声信号组成的数字信号,滤掉150Hz>f>100Hz的频率,计算并显示滤波前后的原始数据波形以及功率谱密度。(A sampling frequency of 2000, a digital signal composed of 50Hz, 120Hz, 200Hz sine and noise signals, is generated to filter out the frequency of 150Hz>f>100Hz and to calculate and display the original data waveforms and the power spectral density before and after the filtering.)
