Abstract
A method and apparatus of this invention changes a frequency at which a control circuit (signal processing circuit) operates in accordance with an operational load of a circuit. More specifically, a pager comprises a signal processing circuit for detecting a first signal sequence within received signals by comparing the received signals with codes originated in the pager and for identifying a second signal sequence received in association with the first signal sequence within the received signals, the signal processing circuit being supplied with a first clock signal having a first frequency when the signal processing circuit detects the first signal sequence and being supplied with a second clock signal having a second frequency when the signal processing circuit identifies the second signal sequence. Still, the frequency applied to the signal processing circuit may be changed in accordance with the operational load of the circuit.
