Abstract:
A method to cancel amplitude modulation noise (contamination) of an input (carrier) signal, including: receiving an input monochromatic signal contaminated with amplitude modulation noise; demodulating the amplitude modulation noise to generate a baseband amplitude modulation noise signal; signal processing the baseband amplitude modulation noise signal to generate an amplitude modulation noise cancelation signal; and amplitude modulating the input signal based on the amplitude modulation noise cancelation signal to generate an output signal, the output signal having less amplitude modulation noise than the input signal. A feedforward implementation can use signal inversion to generate a feedforward amplitude modulation noise cancelation signal. A feedback implementation, implemented with a gain controlled amplifier, can be based on, in a feedback path, demodulating the amplitude noise modulation signal in a feedback gain-controlled input signal to generate a feedback gain control signal.
