| Abstract: | This paper analyse an abnormal inverting phenomenon in differential circuit experiment and measurement error caused by this phenomenon. Restrain ability to solve ploblems of source fluctuating and frequence interference signals of two kinds of bridge amplifiers composed by operational amplifier are discussed, and put forward a new way to advance restrain interference ability of bridge amplifiers, the theoretial results are in good agreement with that from experiment. |
