摘要：
Signal modulation apparatus for applying a modulation signal to a carrier signal, the apparatus comprising: an amplitude modulator for modulating the amplitude of the carrier signal in accordance with a control signal; first mixing means for mixing together fractions of the carrier signal before and after action of the amplitude modulator to produce a first detection signal indicative of the amplitude modulation applied by the amplitude modulator; and detection means for comparing the control signal with a first detection signal to evaluate distortion in the first detection signal as compared with the control signal.
