利用matlab进行信号采样（欠采样、过采样等）的源程序-Sampling the signal using matlab (less sampling, oversampling, etc.) of the source

MATLAB实现连续信号采样、频谱分析和采样信号恢复的方法。计算在临界采样、过采样、欠采样三种不同条件下恢复信号的误差，并由此总结采样频率对信号恢复产生误差的影响，从而验证时域采样定理。-MATLAB continuous signal sampling, spectral analysis and sampling signal recovery method. Calculated in a critical sampling, the oversampling signal error r
