ABSTRACT:
A circuit for reducing transmitted and radiated impulse noise which is generated by opening and closing connections between a transmission path and a source of potential. In the case of closing such a connection a path is connected to a substantially zero potential and the potential is increased to the operating potential over a preset period of time. In the case of opening such a connection the connected potential is decreased to substantially zero over a preset period of time and the path is opened. A potential control circuit is connected between the battery side of the transmission path and the source of potential and the control thereof is coordinated with the connecting means to achieve the described sequences.
