摘要： A method of adjusting signal processing in a receiver based on signal strength includes determining a received signal strength indicator (RSSI) level, defining an RSSI value to be high when the RSSI level is above a first threshold or defining the RSSI value to be low when the RSSI level is below the first threshold, determining an automatic gain control (AGC) gain level, defining an AGC value to be high when the AGC gain level is above a second threshold or defining the AGC value to be low when the AGC gain level is below the second threshold, and adjusting power consumption of one or more receiver stages based on the RSSI value and the AGC value.

摘要： A receiver is set forth that includes a tuner circuit and a converter circuit. The tuner circuit provides an analog signal corresponding to a modulated signal that is received on a selected channel. The converter circuit includes a sample clock that is used to convert the analog signal to a digital signal at a conversion rate corresponding to the frequency of the sample clock. The sample clock is selectable between at least two different clock frequencies.
