Named after French mathematician and physicist Jean Baptiste Joseph Fourier, who initiated the study of what is now harmonic analysis.
noun Fourier transforms · FT
- A particular integral transform that when applied to a function of time (such as a signal), converts the function to one that plots the original function's frequency composition; the resultant function of such a conversion. Fourier transforms are not limited to acting on functions of time, but the domain of the original function is commonly called the time domain.
