| 摘 要： | 取样定理是把模拟信号变成数字信号取样频率选取的一条重要准则．本文选取一模拟信号，在Matlab平台上用不同的取样频率对其采样，并利用三次样条函数对取样信号进行重建，将重建出的连续信号与原连续信号相比较，从而在Matlab平台上实现了取样定理的仿真说明．

| Abstract: | The sampling theorem is a principle of choosing the sampling frequency in changing analog signal into digital signal.The text chooses a analog signal,it is sampled by different frequency;so the continous signal can be reconstructed by the sampling signal.The text compares the reconstructed contious signal with the primary contious signal,a satisfactory result has been gained by neans of programming and simulation in Matlab. |
