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2个测量周期信号相位差的仿真程序。仿真测量数据相对误差约为0.3%,与传统的方法相比,具有精确程度高,抗干扰能力强,易于实现等优点。
Using Fast Fourier Transform (FFT) algorithm and relevant functional operation, and based on LabVIEW platform, 2 simulated programs are designed to measure the phase difference of periodic signals. With about 0.3% relative error in the data from simulated measurement, this design is superior to traditional ones with a higher degree of precision, a stronger anti-jamming capability, and an easier access to achievement
