Abstract

984, 349. Integrating circuits. MARCONI CO. Ltd. Sept. 23, 1963 [Oct. 16, 1962], No. 39053/62. Heading G4G. In order to establish the voltage rest level of a conventional integrating circuit which contains a resistance 2 and condenser 1 in series, with a D.C. amplifier 3 and a switchable shunt circuit in parallel across the condenser, a predeterminable D.C. potential is applied to a suitable point in the switchable shunt circuit. The switchable shunt circuit may include a transistor switch 6 and a repeater 13 of unity gain and the D.C. may be applied from an adjustable potentiometer 14 across a D.C. source. When the transistor is switched on, the integrating circuit is returned to the rest level set by the adjustable potentiometer. Specifications 984,347 and 984, 348 are referred to.
