摘要： A received plurality of signals may be filtered to select an in-band signal and/or an out-of-band. A signal strength of the selected signal(s) may be measured. A resolution of an analog-to-digital converter may be controlled based on the measured signal strength(s). The selected in-band signal may be converted to a digital representation via the analog-to-digital converter. The resolution may be decreased when the strength of the in-band signal is higher, and increased when the strength of the in-band signal is lower. The resolution may be increased when the strength of the out-of-band signal is higher, and decreased when the strength of the out-of-band signal is lower. A signal-to-noise ratio and/or dynamic range of the selected signal(s) may be determined based on the measured signal strength(s), and may be utilized to adjust the resolution of the analog-to-digital converter.
