AN APPARATUS FOR ELIMINATING INTERFERENCE CAUSED BY SPURIOUS SIGNALS IN COMUNICATION SIGNALS

摘要

An apparatus for eliminating interference caused by spurious signals includes a reference oscillator (127) and a controller (114). Circuitry (500) in a communication device (104) incorporating the apparatus operates at a rate set by a system clock signal (CLOCK). The communication device (104) communicates on any one of a plurality of different channels. The reference oscillator (127) outputs the system clock signal (CLOCK) at a first frequency which generates spurious signals on at least one of the plurality of different channels. The controller (114) shifts the system clock signal (CLOCK) by a first predetermined amount to a second frequency when the communication device (104) is to be tuned to the at least one of the plurality of different channels so as to remove the spurious signals from the at least one of the plurality of different channels.
