说明： 数字信号处理设计与仿真分析
(1)建立两个模拟信号的数学模型 sa1(t)和 sa2(t)， 其中 sa1(t)是有用信号， sa2(t)是干
扰信号。 两个信号的中心频率、信号带宽等参数由学生自己选定，要求两个信号的频谱不重
叠， sa2(t)的幅度比 sa1(t)的幅度高 20dB， 两个信号时域叠加得到合成信号 xa(t)， 即
xa(t)= sa1(t)+ sa2(t)
设计计算机程序仿真产生 sa1(t)、 sa2(t)、 xa(t)信号， 分别画出三个模拟信号的时域波
形和频谱图；(Establish two mathematical models of analog signals sa1(t) and SA2 (t), where SA1 (t) is the useful signal and SA2 (t) is the dry signal
Interference signals.)
