Abstract
The invention provides a method, system and electronic equipment for improving the conversion precision of low-frequency frequency signals, belonging to the technical field of communication. The method includes: setting the conversion time period of the low-frequency frequency signal by parameterization; using standard high-frequency frequency signal sampling to generate a new low-frequency frequency signal F; finding the rising edge of the low-frequency frequency signal F, and according to the low-frequency frequency signal F The rising edge of the rising edge generates a counting and sampling start flag; generates the counting of the starting sampling time; keeps the counting time consistent with the conversion time period of the low-frequency frequency signal F, and generates a counting time stop signal; stops the signal according to the counting time until it is sampled to the next Until the rising edge of a low-frequency frequency signal F, a sign to stop counting is generated, and the counting of the low-frequency frequency signal F and the counting of the standard high-frequency frequency signal are stopped, thereby improving the conversion accuracy of the low-frequency frequency signal. The invention solves the problem of asynchronous processing of frequency conversion.
