| Abstract: | In this paper,we will analyse the negative effect of statistical fluctuation in analogue circuit gauge. Fluctuation can make the control operation unreliable. A lagged-demand comparator may be mainly recomended. If this comparator was added to the circuit, the reliabity of control operation can be improved. Mean while, the usage of this comparator can eliminate many interference signals. |
