WebFeb 5, 2024 · A frequency has to be many times stronger than it would be in a random data set to be taken seriously. A Fourier transform is based on a mathematical theorem that any signal can be decomposed into an infinite number of sine waves. This means that Fourier analysis works best when the signal we are looking for is very similar to a sine wave. WebThis same technique of “Fourier Transformation” is often used in computerized power instrumentation, sampling the AC waveform (s) and determining the harmonic content thereof. A common computer algorithm (sequence of program steps to perform a task) for this is the Fast Fourier Transform or FFT function.
