Abstract

PURPOSE: To prevent the reduction of the noise allowance by varying the threshold voltage of the reception circuit according to the state of the code row of the reception signals.
CONSTITUTION: The code is identified with every bit at reception circuit 12 for the reception digital signals given from input terminal 11, and thus the output signal is obtained at output terminal 13 and 14 each according to the high or low level of each bit of the reception signals. In this case, up-down counter 15 has the up-count and the down-count by the output of terminals 13 and 14. The count contents of counter 15 is converted into the analog signals through D/A converter 16, and this analog signal is applied when necessary to threshold voltage input terminal 18 of circuit 12 via amplifier 17 and in the form of the threshold voltage. As a result, the reduction of the noise allowance can be prevented.
