本文根据付里叶变换的时延性,采用软件来消除各通道振动信号间的相位差,适用于任何通道数据采集系统的相位差补偿,不受A/D板和其它设备性能的限制,简单直观,易于推广应用
According to the time delay of Fourier transform, this paper uses software to eliminate the phase difference between the vibration signals of each channel. It is suitable for the phase difference compensation of any channel data acquisition system. It is not limited by the performance of A / D board and other devices. , Easy to promote the application
