According to the FOURIER THEOREM, periodic sound may be shown to consist of SINE WAVEs in the HARMONIC SERIES ... a time-domain signal to the frequency domain is called the Fourier transform. Compare: ...

While the Fourier transform gets all the attention, there are other transforms that engineers and mathematicians use to transform signals from one form to another. Sometimes you use a transform to ...

which is reasonably continuous may be expressed as the sum of a series of sine or cosine terms (called the Fourier series), each of which has specific amplitude and phase coefficients known as Fourier ...

The FFT/IFFT/DCT engine is an application specific instruction set processor (ASIP) optimized for the implementation of Fourier and cosine transforms, while also supporting general FIR equations. ...
