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.
