What is the result of FFT?
The FFT function returns a result equal to the complex, discrete Fourier transform of Array. The result of this function is a single- or double-precision complex array.
What is Fourier in forecasting?
Fourier analysis is a mathematical technique that decomposes complex time series data into components that are simpler trigonometric functions.
What does FFT show on oscilloscope?
The Fast Fourier Transform (FFT) converts time domain waveforms, acquired in an oscilloscope, into frequency domain spectra. This allows the oscilloscope to display the same kind of information usually supplied by an RF spectrum analyzer.
