Abstract
PURPOSE: To realize the simultaneous transmission/reception of multiple aural signals of time division by giving a syncrhonous switching to the AM modulation waves of multiple languages via the ring counter circuit.
CONSTITUTION: The aural signals of multiple languages are amplified through the microphone for simultaneous interpretation or the like, and the output gives the amplitude modulation to the color subcarrier. Then the synchronous switching is given to these output by horizontal synchronous signal HSP and via ring counter circuit RCS. This switching is carried out the position where the current of the modulated wave is zero by controlling the phase of the switching pulse. In such way, the switching is possible at the joint of the AM modulation wave of each language, thus producing no kick voltage.
