Transistorized Binary Pulse Regenerator

Abstract

A simple transistorized device has been constructed for amplifying and regenerating binary code signals as they are transmitted over substantial lengths of transmission line. By the use of simple circuitry, means are provided whereby the distortion in the output of one repeater due to low frequency cutoff is compensated in the next repeater. Furthermore, the repeater is effectively and simply timed from its own regenerated output. A brief discussion of the theory of the circuit is presented along with measured results and oscillograms showing its performance. The effects of extraneous interference on the production of errors in such a repeater are reported. These results are in substantial agreement with theory.
