Fourier transform
Fourier transform noun: 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.
Noun
Fourier transform (plural Fourier transforms)
- 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.
- The Fourier transform of a function of time is a complex function of frequency, whose magnitude (absolute value) represents the amount of that frequency present in the original function, and whose argument is the phase offset of the basic sinusoid in that frequency.
