Abstract

PURPOSE:To prevent the production of reflection waves between two wires and ground of a balanced transmission line and to enable accurate information transfer, by connecting resistance and a capacitor in series between the neutral point of the termination resistance and ground, in a DC coupling balanced transmission line. CONSTITUTION:At both the ends of a balanced transmission line B, the values of resistances R2-4 and of a capacitor C are selected so that a characteristic impedance Zb between two wires and a characteristic impedance Zu between two wires and ground can be matched with the matching and terminating circuit. Thus, against a signal or external noise produced between two wires and ground of a balanced transmission line B, negative reflection waves have no possibility to the produced, and the output impedance of a transmission circuit DV is avoided from being a low value.
