Abstract:
1. A signal receiver capable of operating in two modes: a normal mode for reception and decoding of signals and a detection mode for detecting the presence of signals, the signal receiver having: at least a power supply that can operate in two manners: a first manner having relatively low power consumption and relatively poor accuracy and a second manner having relatively high power consumption and relatively high accuracy, and a controller for causing said clock, power supply or filter to operate in the first manner when the receiver is in its detection mode and in the second manner when the receiver is in its normal mode; wherein said power supply comprises two components each capable of providing the function of the power supply, the first of the components providing the function in the first manner, having relatively low power consumption and relatively poor stability, and the second of the components providing the function in the second manner, having relatively high power consumption and relatively high stability; wherein only said first of the components is operational when the receiver is in its detection mode.
