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obtained by decomposing a … See more The development of fast algorithms for DFT can be traced to Carl Friedrich Gauss's unpublished work in 1805 when he needed it to interpolate the orbit of asteroids Pallas and Juno from sample observations.

WebSal calls the first term, a_0, of the Fourier series the "baseline constant". This is a nickname for the term. In electronics it is also called the "DC offset". The a_0 term is not multiplied by a sine or cosine, so it is just a constant numbered added to the result. If a_0 = 1, f(t) shifts upwards on the y axis. If a_0 = -1 then f(t) shifts down. small post and beam cabinsWebtopic of this chapter is simpler: how to use the FFT to calculate the real DFT, without drowning in a mire of advanced mathematics.
