A transceiver includes a receiver and a transmitter. The receiver includes an analog-to-digital conversion device for converting a received analog signal to digital form, and the transmitter includes a digital-to-analog conversion device for converting a digital signal into analog form for transmission. A selector selects the resolutions of the conversion devices. The resolution of the analog-to-digital conversion device is selected based on a received signal quality, e.g., the signal-to-noise ratio or the signal-to interference ratio. The resolution of the digital-to-analog conversion device is selected based on a crest factor of the transmitted signal, the crest factor depending, e.g., on the modulation format of the signal being transmitted. The higher the crest factor, the higher the resolution selected.
