Summary:A receiver (10) for receiving a wireless communication signal, such as a UWB signal, is operable in a first mode when the receiver is actively receiving a transmitted signal, and a second mode when the receiver is waiting to receive a transmitted signal. The receiver comprises an analogue-to-digital converter (20) for converting a received analogue signal into a digital signal. A receiver controller is adapted to control the operating resolution of the analogue to digital converter such that, in the first mode, the analogue-to-digital converter (20) operates at a first resolution, and, in the second mode, the analogue-to-digital converter (20) operates at a second resolution. The second resolution is lower than the first resolution, and preferably the second resolution is a 1-bit resolution.
