1 day ago · Definition The Fourier transform is an analysis process, decomposing a complex-valued function f (x) {\displaystyle \textstyle f(x)} into its constituent frequencies and their amplitudes. The inverse process is synthesis, which recreates f (x) {\displaystyle \textstyle f(x)} from its transform.
