Unity amplitude

{{more citations needed|date=January 2019}}

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

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

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, $\backslash alpha$, and a defined fundamental period, $T\_o$.

Analytic signals with unit amplitude satisfy the Bedrosian Theorem.Huang et al. On Instantaneous Frequency: http://rcada.ncu.edu.tw/2009%20Vol.1_No.2/1.ON%20INSTANTANEOUS%20FREQUENCY.pdf
