ABSTRACT:
Disclosed is a selective calling reception apparatus which comprises an intermittent reception oscillator for intermittently receiving a selective calling signal from a base station and a signal processing oscillator for processing the selective calling signal, in which the oscillation of the signal processing oscillator is controlled in accordance with a timing signal generated on the basis of the oscillation output of the intermittent reception oscillator. Accordingly, when the transmission rate of a selective calling signal is made high, it will do to make only the oscillation frequency of the signal processing oscillator high and it is not necessary to make the oscillation frequency of the intermittent reception oscillator high to thereby make is not required to be made high, so that the current consumption at the stand-by time does not increase.
