Continuous offset correcting system in binary digital transmission. Especially applicable to receivers included in binary digital transmission systems with access (DBTA) which have a discriminator which provides the signal to a decider which compares this signal with a decision threshold and which has as its object the establishment of the optimum decision threshold. They have an analogue/digital converter 1 which obtains samples per bit which is connected to the discriminator and to a retard circuit 2 which retards the signal samples by one bit period. The analogue/digital converter 1 and the retard circuit 2 are connected to a summator circuit 3 and to the differentiating circuit 4 which in turn are connected to a control circuit 5, which same is connected to the analogue/digital converter 1 and to the decider 6 in order to detect the offset sign and modify the comparison threshold level of the decider 6. <IMAGE>
