A Device for Offsetting High Level Electrical Interferences in Low Level Detectors

It is often useful to maintain an analogue output of a signal which has excessive noise. At near D.C. frequencies, this is seldom possible. However, when the noise can be identified, two ways of correcting this situation are immediately available. The first is to eliminate the interference at the source and the second is to supply appropriate offset to this interference. In the case of high-level energy sources, it is virtually impossible to eliminate their interference and it becomes necessary to fabricate electrical offsets to do this. This procedure is well-established in electronics and is used extensively in operational amplifiers.
