RADIO SIGNAL RECEIVING APPARATUS AND RADIO SIGNAL RECEIVING METHOD

摘要

Herein disclosed is a radio signal receiving apparatus for receiving radio signals each having a base band signal component, comprising: radio signal amplifying means for amplifying the radio signals each having a signal level; base band signal producing means for producing base band signals respectively indicative of the base band signal components of the radio signals amplified by the radio signal amplifying means, the base band signals each having a signal level; controlling means for controlling the radio signal amplifying means to have the radio signal amplifying means amplify the radio signals in response to the signal level of each of the base band signals to be produced by the base band signal producing means; base band signal selecting means for periodically selecting one of the base band signals from among the base band signals produced by the base band signal producing means in response to the signal level of each of the radio signals; and base band signal outputting means for outputting the base band signal periodically selected by the base band signal selecting means to an exterior device.
