Abstract

Based on the analysis of sine or quasi-sine period signal zero crossing point detecting of computer-based detecting and control system, Fourier transform is employed to get input signal's key spectrum to build waveform characteristic dictionary, and the signal's differentia can supply more information of input signal's zero crossing point. Methods are proposed referring to circumstances, and results of simulation prove efficiency.
