WebIf my current signal is x, I did FFT using the equation FFT_x = abs (fft (x)/sqrt (N)) where I N = length (x), e.g., length of my current signal. But I do not get any peak at my operation frequency (2 GHz) and not even in any … A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa. The DFT is obtained by decomposing a sequence of values into components of different frequencies. This operation is useful in many fields, but computing it directly from the definition is often too slow to be practical…
