生成一定参数的原信号，分别通过等采样间隔，过采样间隔，欠采样间隔，对原信号进行采样，分析结果，验证了奈奎斯特采样定理。-Certain parameters of the original signal is generated, respectively, through the other sampling interval, over-sampling interval, due to the sampling interval of the original signal is sampled, the analysis result, verify the Nyquist sampling theorem.
