Abstract

PURPOSE:To perform two-way communication only by providing an oscillating circuit, output amplifying circuit and receiving filter by assigning carrier frequencies adjacently. CONSTITUTION:The output of control signal generating circuit 35 is modulated by modulating circuit 32 at a relatively high frequency and the modulation output is transmitted to unit 50 by way of output filter 34. The output of controlled unit, on the other hand, is modulated at a relatively low frequency and transmitted to terminal unit 41 and the operation confirmation signal from controlled unit 45 is displayed by display circuit 40.
