Abstract
A radio receiver receives information on a radio carrier and switches portions of the receiver (12, 14, 18) OFF and ON at a rate greater than the bandwidth of the information, thereby reducing the power consumed by the radio receiver. A signal quality detector (42) determines the amount of distortion introduced by the switching and controls a duty cycle modulator (44) in order to maximize the OFF time while maintaining adequate signal quality. If receiving a data transmission, a synchronizer (46) may be used to synchronize the switching to the bit timing. A transmission gate (24) and capacitor (26) holds the input of filter (32) constant while portions of the receiver are OFF or generating transients due to being switched ON.
