Web本实验仅在时域求解。在计算机上适合用递推法求差分方程的解，最简单的方法是采用 MATLAB语言的工具箱函数filter函数。也可以用MATLAB 语言的工具箱函数conv函数计算输入信号和系统的单位脉冲响应的线性卷积，求出系统的响应。 Web3 DFT and IDFT In order to compute the DTFT of a signal x[n] using MATLAB the signal x[n] must be rst truncated to form a nite length signal. This is not necessarily a limitation since in real life applications, we only have nite recordings of sampled and quantized (i.e. digitized) continuous time signals.
