Unity amplitude
From HandWiki
A sinusoidal waveform is said to have a unity amplitude when the amplitude of the wave is equal to 1.
[math]\displaystyle{ x(t) = a \sin(\theta(t)) }[/math]
where [math]\displaystyle{ a = 1 }[/math]. 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, [math]\displaystyle{ \alpha }[/math], and a defined fundamental period, [math]\displaystyle{ T_o }[/math].
Analytic signals with unit amplitude satisfy the Bedrosian Theorem.[1]
