ABSTRACT:
A remote fed intermediate regenerator for use in transmission lines for digital signals having no direct current component has for each transmission direction a series circuit including a distortion corrector a regenerator circuit and a transmitting amplifier. For isolating the signal path and the remote feed path each intermediate regenerator is preceded and followed by remote feed dividing filters and each intermediate regenerator contains a high power Zener diode bridging the remote feed path of the regenerator and the distortion correcter and regenerator circuit each contain low power Zener diodes for stabilizing the operating voltages thereof. A transmitting amplifier for the intermediate regenerator has dynamic current characteristics and operates to stabilize the voltage without the necessity of a Zener diode and accordingly does not require a high-value input impedance thereby avoiding a significant power loss.
