Patent abstract
A signal is modulated by generating a pulse-width modulation signal and applying the pulse-width modulation signal to an input of a switched-mode amplifier. An output of the amplifier is coupled to a filter operable to impart either differential mode oscillations or common mode oscillations at the amplifier output based on the duty cycle of the pulse-width modulation signal. The duty cycle of the pulse-width modulation signal is varied to impart amplitude modulations at the amplifier output.
