Design and error analysis of a fast phase difference detection algorithm for sinusoidal characteristic signal

Abstract

The paper mainly explains a fast detection algorithm of sine wave phase difference applied to embedded equipment and applies the algorithm to practical engineering. It samples and compares the data in the actual environment, gives the deviation between the calculation result of the algorithm and the theoretical value under different conditions, different parameters, and different sampling rates, and analyzes and compares the calculation results. The data of the experimental results provide a basis for the subsequent algorithm research. The design of the algorithm provides a new solution for the calculation of the phase difference algorithm in the field of communication.
