A sinusoidal waveform is said to have a unity amplitude when the amplitude of the wave is equal to 1.

$x(t)=a\sin(\theta (t))$

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, $\alpha$ , and a defined fundamental period, $T_{o}$ .

Analytic signals with unit amplitude satisfy the Bedrosian theorem.^[1]
