| 摘 要： | 针对信号系统中求解离散系统和连续系统响应不统一性问题，本文研究了求解离散系统和连续系统响应间的共性，为了能够用像求解连续系统响应的方法解决离散系统响应，提出了通过对离散系统进行简单的变换利用解决连续系统响应的方法解决离散系统响应的方法，并利用MATLAB实现其函数化，进而可以利用此MATLAB函数实现微分方程解差分方程的问题。仿真结果表明，此方法可以很好的应用到离散系统求解响应和求解差分方程中。

| Abstract: | According to block of wood unitarity problem about solving the discrete LTI respond and continuous LTI respond,this paper studies the generality of solving the discrete LTI respond and the continuous LTI respond,In order to solve the discrete LTI respond such as solving the continuous LTI respond,it puts forward a technique of solving the discrete LTI using the method of solving the contin- uous LTI respond,and uses MATLAB function to realize.Then it may solve the difference equation using the method of dif... |
