Abstract
A system and method for reducing signal-to-noise ratio in a multi-component analog signal during analog to digital conversion. The multi-component analog signal is made up of a plurality of separate analog signals, with each of the separate analog signals having separate amplitude levels. A reference gain control signal, corresponding to the largest amplitude component of the multi-component signal, is first determined. Next, the reference gain control signal is used to generate a gain control signal. The gain control signal is then used to adjust each component of the multi-component signal by a gain value. Finally, the gain adjusted signals are converted to corresponding digital signals.
