PURPOSE:To increase the transmission efficiency of data, by giving the output of an automatic gain adjusting circuit to a resonance circuit, after saturation period by leading response when a multi-phase modulation signal is given to the automatic gain control circuit. CONSTITUTION:A switch 9 is inserted between an AGC2 and a nonlinear circuit 3. Further, the switch 9 is operated with the time-up output of a timer circuit 10 started with the output of a carrier detection circuit 6, and the input of the nonlinear circuit 3 is switched from a termination resistor 11 to the output of the AGC2. After the period adding some allowance period to the saturation period of the AGC2, the timer circuit 10 produces the time up output (g) and the switch 9 is operated by it. |
