| Abstract: | 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 |
