摘要
Abstract
Output signal of accelerometer which is used for over-loading signal test system is often mixed with noise. The mismatch of bidirectional accelerometer and single direction of over-loading signal leads to the full-scale of AD converter cannot be put into full play. Aiming at these problems,a kind of conditioning circuits is developed to re⁃duce noise,increase signal to noise ratio and regulate signal amplitude accurately. Test results show that stop band attenuation is up to-69.19 dB,when the input frequency is twice of the cutoff frequency. Accuracy of stationary sig⁃nals regulation is controlled within 1%. This circuit has been successfully applied in engineering practice.关键词
