Abstract: An electronic hybrid circuit for coupling a two-wire communication path with a four-wire communication path is disclosed wherein the use of transformer coupling is eliminated. The hybrid features a novel arrangement whereby the unbalanced four-wire path incoming voice signal is amplified, then converted to a pair of balanced signal components by complementary signal injection devices coupled to opposite sides of the two-wire path. Each resultant balanced component is injected in series with a DC battery feed potential via current amplifiers in each signal injection means. Balanced two-wire path output signals are converted for transmission to the outgoing portion of the four-wire path by coupling the two-wire path to the series combination of a differential amplifier and an output buffer amplifier.
