A signal coding technique for switching amplifiers includes quantizing the amplitude A(t) of an input signal to produce a time series Â(t) having M levels; modulating a clock signal in response to Â(t), thereby to produce a control signal; switching among at least three different power supply output levels in response to the control signal, thereby to generate an output pulse stream; and filtering the output pulse stream to produce an output signal for transmission.
