摘要
利用快速傅里叶变换(FFT)算法和相关函数算法,基于LabvIEW平台,设计了两个测量周期信号相位的程序。仿真结果是测量数据相对误差在0.02%左右。
Using Fast Fourier Transform(FFT) algorithm and correlation algorithm,Two programmes of signal phases during measuring period were designed on the basis of LabVIEW. Experimental results show that the relative errors of the measuring data are about 0.02％.
