摘　　要：该文基于MATLAB再现了连续信号的采样频谱和重构的时域信号，给出了信号重构的误差，并分析了采样周期对采样频谱叠加和信号重构精度的影响。This text reconstructed frequency spectrum and the signal of a continuous signal based on MATLAB, gave the error of reconstructing signal, and analyzed the influence of sample period on superposition of the frequency spectrum and precision of sampling signal reconstruction.

关 键 词：信号采样 MATLAB 采样周期 频谱 信号重构
