Method for realizing dynamic sampling rate adjustment by oversampling

The invention relates to a method for realizing dynamic sampling rate adjustment by oversampling. In the method, high-rate sampling is performed on signals to be detected, and effective data are extracted from the signals acquired by the oversampling by combining with the sampling requirement. The requirement of the sampling point of the method for realizing the dynamic sampling rate adjustment by the oversampling comprises sampling rate under a standard cycle and sampling rate which corresponds to frequency tracking when the frequency of a sampling signal is changed. The method for realizingthe dynamic sampling rate adjustment by the oversampling has the beneficial effects that not only is the running load of a digital signal processor reduced, but also a sampling module can be conveniently applied to other occasions.
