Abstract

PURPOSE:To exactly regenerate an original signal by means of a reverse correction, by compressing a signal by a transmission side when an amplitude variation rate of an input signal is large, and detecting the extent of signal compression from a variation rate of amplitude information of a demodulation signal by a receiving side. CONSTITUTION:In case when an output of a differentiating circuit 19 eceeds an upper limit value which has been set by a level deciding circuit 20, a transmitter side makes the gain of an amplitude controlling circuit 18 smaller than ''1'', and makes the gain of the circuit 18 larger than ''1'' when an output of the circuit 19 becomes lower than a lower limit value which has been set by the circuit 20. In case when an output of a differentiating circuit 21 exceeds an upper limit value which has been set by a level deciding circuit 22, a receiver side makes the gain of an amplitude controlling circuit 23 smaller than ''1'', and makes the gain of the circuit 23 larger than ''1'' when an output of the circuit 21 becomes lower than a lower limit value which has been set by the circuit 22.
