Abstract
An apparatus for controlling an amplitude of a signal generated from a digitized sinusoid of rapidly and widely varying amplitude is described herein. The apparatus includes a two stage gain adjuster which produces a gain adjusted signal, a phase shifter which converts the gain adjusted signal into two gain adjusted output signals separated in phase by 90 degrees, a power estimation unit to estimate the power of the gain adjusted signal, and an adjusting unit to adjust a gain of the gain adjuster according to a power estimate from the power estimation unit and a desired output signal power.
