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.)

Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.
