ZWEIMODENEMPFÄNGER MIT BATTERIESCHONUNGSMÖGLICHKEIT

摘要

A dual mode communication receiver comprises a first demodulator (108) for detecting information transmitted in an FM modulation format on a first channel, and a second demodulator (112),responsive to the information detected in the FM modulation format, for detecting information transmitted in a linear modulation format on a second channel. The first and second demodulators(108,112) share a common receiver front end. A power conservation circuit(104) is provided for selectively supplying power to the first and second demodulators for enabling the detecting of the information received in the FM modulation format and the linear modulation format, respectively.
