摘要
介绍了 G- N线检测仪的实用意义和工作原理。对含有大量干扰的输入信号作了分析。在采用有源滤波的基础上 ,进一步利用数字滤波和对输入信号线性累加的软件处理 ,提高了信噪比 ,从而提高了 G- N线检测仪的抗干扰能力和判断的准确度。
This paper introduces the practical worth and working principle of the G N Line Determination Meter, analyzes the input signal included mass disturbance. On the base used active filter, and use digital filter and software processing of linear superposition to the input signal. Increase signal to noise ratio and so increase anti interference capability and appreciation accuracy of the G N Line Determination Meter.
