摘要
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。
The paper reconstructs frequency spectrum and reconstructing signal of a continuous signal based on MATLAB ,presents the error of reconstructing signal,and makes an analysis of the influence from sampling period on the superposition of frequency spectrum and precision of sampling signal reconstruction.
