Abstract

PURPOSE:To make a titled device small, to make wiring works easy, and to reduce the cost, by enabling to operate a system with the fundamental wave of one type of frequency, through the addition of a simple digital gate and a digital frequency converter and the like to a carrier device. CONSTITUTION:To a carrier device which produces carrier wave based on the fundamental wave of the 1st frequency, is added a frequency divider and an exclusive logical sum gate 7, and the fundamental wave of the 1st frequency passes through the AND gate 5 and the exclusive logical sum gate 7 and apperas at an output terminal 9 as it is at the input of the fundamental wave. When the fundamental wave of the 2nd frequency other than the 1st frequency is inputted, since logical 1 is given to one input of an AND gate 13 from a control input terminal 3, the 2nd frequency is converted into the 1st frequency at a 1/31 frequency division circuit 15 and added to one input of the exclusive logical sum gate 7 through an AND gate 17. Since other inputs are at logic 0, the frequency-divided fundamental wave passes through the gate 7 and appears at an output terminal 9. Thus, the carrier device can be operated with one type of frequency of the fundamental wave.
