Abstract

713,615. Delay networks. STANDARD TELEPHONES & CABLES, Ltd. Oct. 17, 1952 [Oct. 20, 1951], No. 26103/52. Class 40 (8). [Also in Group XL(c)] A circuit for reducing the overshoot when a pulse is transmitted through an inductive coupling circuit comprises a delay network connected across the coupling circuit and terminated at its distant end so that pulses of a given polarity are suppressed. The Figure shows a circuit in which positive pulses from a driving tube are passed via a transformer 1, 3 to an output 4. The overshoot which would normally follow each positive pulse due to the inductive reactance of the coupling circuit 1, 3 is reduced by the delay network 8 which is terminated in its characteristic impedance by resistor 13 across which rectifier 14 is connected. Positive pulses occuring across terminals 11, 12 are transmitted down delay network 8, which has a one way delay time equal to a fraction of the output pulse duration, are reflected at diode 14, with a change in polarity and appear back at the input terminals as negative pulses. The overshoot due to each negative pulse applied across terminals 11, 12 counteracts that caused by the applied positive pulses so that the overshoot is effectively cancelled. Any transmission of negative pulses down delay network 8 is dissipated in impedance 13 since diode 14 presents an output circuit to such pulses. The one-way delay time of network 8 is preferably equal to one-half the input pulse duration; if it is made less than this the circuit will also function as a pulse narrowing circuit.
