WebThe Fast Fourier Transform (FFT) is an algorithm which performs a Discrete Fourier Transform in a computationally efficient manner. It requires a power of two number of samples in the time block being analyzed (e.g. 512, 1024, 2048, and 4096). ... A Fourier Transform of a sine wave produces a single amplitude value with corresponding phase … WebThis is what the FFT gives you. For example, if you sum sin (2*pi*10x)+sin (2*pi*15x)+sin (2*pi*20x)+sin (2*pi*25x), you probably want to detect the "frequency" as 5 (take a look at the graph of this function). However, the FFT of this signal will detect the magnitude of 0 for the frequency 5.
