Fisher's method

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, α, and a defined fundamental period, T_o.
