In mathematics, Fourier analysis (/ f r i e,-i r /) is the study of the way general functions may be represented or approximated by sums of simpler trigonometric functions.Fourier analysis grew from the study of Fourier series, and is named after Joseph Fourier, who showed that representing a function as a sum of trigonometric functions greatly simplifies the study of heat transfer. If x is a random variable and a distribution, x means that x is distributed according to . For example, if the fundamental frequency is 1.0kHz, then the transient data from the last 1ms cycle would be used for the Fourier analysis. 0.24) that the delta distribution itself has equivalently the following expression as a generalized function.
