Research of Zero Crossing Point Real-time Detecting of Quasi-Sinusoidal Signal

摘要：

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 signals key spectrum to build waveform characteristic dictionary, and the signals differentia can supply more information of input signals zero crossing point. Methods are proposed referring to circumstances, and results of simulation prove efficiency.
