PURPOSE:To prevent overlap of answers by permitting a subordinate station to answer to a call from a master station with an answer delay time that corresponds to a received input voltage of the subordinate station. CONSTITUTION:A calling signal from a master station is led from antenna 1 of a subordinate station to receiver 2 and then converted into limiter voltage 3 proportional to a received input voltage and the limiter voltage is applied to answer delay circuit 4. Circuit 4 forms a time lag in proportion to the input voltage and transmitter 6 is put into operation with its answer actuation signal to make an answer to the master station. |
