IPC: H04B14/06
Filed: 1984-08-30
Abstract: PURPOSE:To quicken error restoration and to prevent deterioration of transmission quality by changing the rate of leakage of an integration circuit in response to the detection of occurrence of error. CONSTITUTION:An input signal (a) given from a transmission line is added with an integration value of an output (c) from a subtractor 4 by an adder 1 and the result is an output signal (d). The output signal (d) is subject to delay by one unit time at a delay device 2 and inputted to a calculation circuit 3 and the subtractor 4. The calculation circuit 3 calculates the leakage amount of the circuit 5 and the leakage of the integration circuit 5 is subtracted from the signal delayed by the subtractor 4. On the other hand, the input signal (a) is inputted to an error detection circuit 6 and the code error of the input signal (a) is detected. A control circuit 7 changes the rate of leakage of the integration circuit 5 in response to the detected code error.
