Abstract
PURPOSE: To ensure an easy selection of the control signals by transmitting the control frequency signals to the selection circuit via the three-winding transformer for rectification and integration and thus actuating the relay to stop the aural answer signals.
CONSTITUTION: The aural output of sural answer signal generation circuit 1 is eliminated through narrow band blocking filter 5 for the frequency corresponding to the control signal frequency sent from the remote side terminal. And for this output, the constant loss component due to the filter is compensated by auxiliary amplifier 6. After this, the output is delivered to the circuit via three-winding transformer 2. While the control signals sent from the circuit are supplied to selection circuit 3 via transformer 2 to actuate relay 4 after rectification 7 and intergration 8 and then stop the aural answer signals given from aural frequency generator 6. Thus the control signal frequency component of the aural answer signals can be suppressed to ensure an easy selection of the control signals.
