Abstract

PURPOSE:To minimize the shape of a modulator and to obtain the interchangeability between mutual modulators by using the output of a common reference frequency oscillator having an oscillation frequency equal to the interval frequency of a multicarrier, and generating and supplying a carrier used at respective modulators. CONSTITUTION:A common reference frequency oscillator 6 with the interval frequency of a multicarrier as an oscillation frequency is provided, the wave of the reference frequency is (n)-multiplied by a multicarrier generating means 7, higher harmonic components are generated, and thereafter, a necessary higher harmonic component is extracted and supplied to respective modulators of a modulating part 8 as a carrier. Thus, since it is not necessary to provide a reference oscillator at respective modulators, miniaturization is obtained and the interchangeability occurs between mutual modulators. Since one reference frequency oscillator to generate the multicarrier may be sufficient, the decrease in the cost of the device is executed.
