FFT测量周期信号的幅值与相角修正

The Correct Value Of Scope and Phase Angle Using FFT Measure Periodic Signals

通过分析用FFT测量周期信号的幅频特性和相角所产生的误差,推导出FFT测量周期 信号时所应修正的各次谐波的真正幅值和相角差.

This paper first analyses the errors of scope and phase angle measurement of periodic signals using FFT, and then infers the Correct Value Of Scope and Phase Angle Using FFT Measure Periodic Signals.
