Abstract

1397789 Negative impedance circuit POST OFFICE 30 Nov 1973 [8 Dec 1972] 56696/72 Addition to 1323711 Heading H3T The circuit -of Specification 1,323,711 is modified by the inclusion of a Zener diode D1 and a further resistor R 16 to reduce the current level at which the transition from the positive to the negative resistance region takes place.
