1. A method for transmitting an input wave comprising the steps of:
- generating two or more signals that represent said input wave when combined;
modulating a carrier wave with at least one characteristic of at least one of said two or more signals to generate a modulated signal;
modulating a phase shifted carrier wave with a characteristic of another of said two or more signals to generate a phase shifted modulated signal;
inputting said modulated signal and said phase shifted modulated signal into an amplifier having at least two amplifying segments;
controlling at least one of said amplifying segments with a digital control signal containing a characteristic of one of said two or more signals that represent said input wave when combined to generate at least one segment output;
controlling at least another of said amplifying segments with another digital control signal containing a characteristic of another of said two or more digital signals that represent said input wave when combined to generate at least one other segment output;
transmitting an output signal based upon said at least one segment output and said at least one other segment output.

Abstract
The invention relates to a system for electromagnetic processing of an input wave involving the steps of receiving a modified signal derived from two or more signals that represent the input wave when combined; and regulating the modified signal using a digital signal containing at least one characteristic of the two or more signals. Embodiments of the invention may utilize in-phase and quadrature phase signals, where the magnitude portion of the signals may be used for regulating the modified signal. The modified signal may be created by modulating a characteristic of the I, Q signals, such as their sign, with an RF or other frequency carrier wave.
