Abstract:
Two methods, manual backing off and capacitor coupling (by cutting off the d.c. component) are usually used to measure a small transient signal superposed on a large electric current. The shortcomings of them are analysed and an automatic current bac...

Abstract:
In this paper, for linear discrete-time systems under uncertain observations, the recursive formulas for linear least mean-square error (LMSE) filter and one-step predictor is derived, when they exist.
