Abstract
Abstract A two-way two-wire repeater is disclosed comprising two oppositely directed amplifiers coupled to a transmission line. The repeater is provided with a series capacitor and diode connected to feed a portion of the signal at the output of a stage of one amplifier to the input of a stage of the oppositely directed amplifier. This feed-across path eliminates the need for ''''hybrid coil'''' coupling by deforming amplifier oscillation into pulses and permitting the pulses to be amplitude or height modulated.
