WebSep 29, 2016 · The FFT is an algorithm that reduces the calculation time of the DFT (Discrete Fourier Transform), an analysis tool that lets you view acquired time domain (amplitude vs. time) data in the frequency domain (amplitude and phase vs. frequency). In essence, the FFT adds spectrum analysis to a digital oscilloscope.

WebIn most data collectors averaging is performed during the FFT process. Unless synchronous time averaging is invoked the time waveform presented on the screen will be the last average taken even if multiple averages are selected in the instrument setup. It is normal therefore to take a single average. Overlap averaging should be disabled.

"WebAccording to the FFT analysis, the main oscillation frequencies of current are 99.5 Hz and 0.5 Hz, which is totally consistent with the theoretical analysis in Section II. Thus, when the PLL phase margin is greater than a certain value, the grid-connected inverter integrated into a weak grid will cause a supersynchronous oscillation. " - Synchronous fft
