Though examples of common signal and sine signal, by the frequency spectrum graph and theoretical analysis, the minimum sample rate of the sampling theorem is made clear.
以一般信号和正弦信号为例，通过理论分析和频谱图示意，对抽样定理中最低抽样率的取值进行了明确的说明。

An efficient method is presented to find the minimum valid samplingfrequency for bandpass sampling of multiband signals in software defined radio (SDR) technology.
The method starts with the theoretically minimumfrequency and searches for the minimum valid samplingfrequency using variable step sizes subject to three non-aliasing constraints.
