TELEPHONE AND LINE VOLTAGE STABILIZING CIRCUIT FOR THE TELEPHONE

摘要

A telephone set comprising an active line voltage stabilizer circuit (4) provided with two output terminals 10-1 and 10-2 between which there is present a constant direct voltage which is independent of the line current. By connecting to these output terminals a series arrangement of a capacitor (14) and a resistor (18) a DC supply connection is obtained which does not affect the AC impedance of the stabilizer circuit between the wires and which shows a considerably lower output impedance than supply points known thus far in an electronic telephone set.
