Unity amplitude

A sinusoidal waveform is said to have a unity amplitude when the amplitude of the wave is equal to 1. $x(t)=Asin(wt)$ where A = 1.

This terminology is most commonly used in [Digital Signal Processing] and is usually associated with the [Fourier Series] and [Fourier Transform] sinusoids that involve a [duty cycle], ɑ, and a defined [fundamental period], T_o.
