Abstract :
The most important part of digital frequency measurement lies in its flexible and accurate algorithm. This paper presents a fast frequency measurement algorithm based on zero crossing method using short data. This method can effectively resolve the inconsistency between the number of sampling and the accuracy and time of frequency measurement. Besides, it proved that this algorithm has a high accuracy and anti-interference ability.
