说明: 首先,建立两个模拟信号的数学模型 有用信号 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 分别画出三个模拟信号的时域波形和频谱图;然后,根据x_a (t)的中心频率和带宽,按照奈奎斯特采样定理选择采样频率fs,分别对信号s_a1 (t)、s_a2 (t)、x_a (t)进行时域采样,得到离散信号s_1 (n)、s_2 (n)、x(n)。利用FFT算法分析离散信号的频谱,分别画出三个离散信号的时域波形和频谱图;
接着,设计数字滤波器H(z),要求该滤波器对干扰信号s_2 (n)的衰减大于40dB。提出滤波器的设计指标,并设计滤波器,给出滤波器的设计结果,绘制滤波器的幅频特性和相频特性曲线,验证滤波器的设计结果是否达到设计指标要求;此外,选择实现数字滤波器H(z)的结构,画出滤波器结构信号流图;然后,将合成信号x(n)输入数字滤波器H(z),按照所选择的滤波器结构,设计计算机程序计算滤波器的输出响应y(n),画出y(n)的时域波形和频谱图;(the synthetic signal x (n) is input into the digital filter H (z). According to the selected filter structure, a computer program is designed to calculate the output response y (n) of the filter, and the time-domain waveform and spectrum diagram of Y (n) are drawn)
