ABSTRACT:
An amplitude modulator for mixing multifrequency signals characterized in that there are combined a mixer for producing a mixed signal by mixing not less than two alternating current signals with different frequency and a signal generator for the modulator to modulate the mixed signal by applying modulation signal to the mixed signal. According to the present invention, the device can be simplified and miniaturized in comparison with the conventional one since the mixer and amplitude modulator are incorporated in the present invention, whereby reliability of the device is greatly improved.
