Title: Low level D.C. amplifier
Inventor: MOOREY ERNEST JAMES
IPC: H03F3/393
Filed: 1983-03-15
Abstract: The input stage of a low-level D.C. amplifier utilises a chopping technique to convert a D.C. input signal into an A.C. signal for initial amplification by an A.C. amplifier (8), the input stage includes a transformer (1) having a centre- tapped input winding (2) with its centre tap (4) connected to receive the input signal, and an output winding (3) connected to the A.C. amplifier (8). The input stage further includes two switching devices (6, 7) arranged for cyclic, antiphase, operation to connect respective ends of the input winding (2) to a signal return line (5), the effect of this being to apply the input signal alternately across the two input-winding halves. As a result, the A.C. amplifier (8) operates during both halves of the chopping cycle and may have considerable loop gain. By making the transformer (1) a step-up transformer, the effective input noise voltage of the A.C. amplifier (8) can be reduced so that the predominant noise voltage is that resulting from the switching-device resistances when conducting. <IMAGE>

Title: Flare correction by control of video system
Inventor: PETERS DAVID LENDON
IPC: H04N5/217
Filed: 1984-12-19
Abstract: Flare in the optical system of a video camera, e.g. in an aircraft simulator, is compensated by adjustment of black level and gain applied to the outgoing video signals. The average scene illumination is determined from an electrical signal related to the fraction of the light split off by probe 11 from the optical input to the camera 13, or to the electrical output from the camera. In either case the signal is low-pass filtered or integrated, and two functions, respectively representing the black level and gain settings required at different average light levels, are derived for application to the camera signal to remove the effects of flare. <IMAGE>
