Abstract
Abstract An electrical, two-terminal, bidirectional amplifier circuit which senses the direction of flow of a signal current through an ancillary source-load loop in which current flow may be bidirectional, to insert a boost voltage additively in series aiding relationship with the signal current irrespective of the direction of current flow in that source-load loop and then senses the instantaneous state of the signal current to control the magnitude of the added power. The amplifier is insensitive to the direction of transmitted intelligence through the source-load loop by the signal current and inserts the boost voltage additively as required, in the face of the interchange of position of the sources and receivers of intelligence with respect to the amplifier terminals as, for instance, in telephone circuitry.
