WebNov 12, 2024 · Fast Fourier Transform (FFT) Any waveform is actually just the sum of a series of simple sinusoids of different frequencies, amplitudes, and phases. A Fourier series is that summation of sine waves; we use Fourier analysis or spectrum analysis to deconstruct a signal into its individual sine wave components. WebFast Fourier Transform, also referred to as FFT, is an algorithm used to compute the DFT (discrete Fourier transform) of a sequence, or its inverse (IDFT). The Fourier analysis converts an input signal from the original domain (generally time or space) to a frequency domain representation and vice-versa. What does a spectrum analyzer do?
