The more general form of transferring the frequency domain to the time domain is termed the inverse Fourier transform. See: COMPLEX TONE, FOURIER THEOREM, HARMONIC SERIES, SINE WAVE. Compare: GRANULAR ...

The representation of a PERIODIC sound or WAVEFORM as a sum of Fourier components (i.e. pure SINUSOIDAL WAVEs). According to the FOURIER THEOREM, periodic sound may be shown to consist of SINE WAVEs ...

Most modern scopes can compute the Fourier transform of a signal, as in the following screen capture. The bottom trace is a simple 10 MHz sine wave. Above it is the Fourier transform. Unlike a normal ...
