Abstract

PURPOSE:To decrease the vibrating reed filter, amplifier and rectifying circuit in the slave station, by controlling the time width of one of the two parallel signals in matching with the types of selective control and delivering it from the master station. CONSTITUTION:One of the two parallel signals f1, f2 performing the control of some kinds is controlled for the delivery time of the signal in matching with the types of selective control. The third wave succeeded to the signals f1, f2 is delivered from the master station as the tone signal f3 specific to the selective control station to perform the selection control at the terminal. When the signal from the radio unit enters the input terminal 1, it is fed to the vibration filter 3 via the buffer amplifier 2. The time of the output is fed to the clock generation circuit 9 to count it at the counter 8 when the signal of f1, f2 is received at the same time via the amplifying and rectifying circuit 4. The output of the counter 8 is discriminated at the logic circuit 10.
