ABSTRACT:
A receiver includes a signal-receiving section for receiving input signals and outputting detection signal, and a power source for supplying power thereto. A first detector detects a preamble of each input signal while a second detector detects the end of a postamble of each input signal. A power supply section supplies the power to the signal-receiving section by turning on a switch connected between the signal-receiving section and the power source when the first detector detects the preamble of the input signal. A periodic power-supply section turns on the switch periodically to supply the power periodically to the signal-receiving section when the second detector detects the end of the postamble of each input signal.
