Abstract

1,273,988. Transistor differential amplifier; analogue storage circuits. ADVANCE ELECTRONICS Ltd. 2 Oct., 1969 [2 Oct., 1968], No. 46791/68. Heading H3T. [Also in Division G1] The output of a bridge 10, Fig. 2, is fed on alternate half cycles of a power supply 56 to capacitors 19 and 20 via gates 64, 65. The stored signals on capacitors 19 and 20 pass to a differential amplifier 72, 74, 75, 73, 76, 77, including a balancing potentiometer 78, having an output across terminals 83.
