摘要
介绍动平衡仪中弱信号提取的门积分器的设计。讨论了门脉冲宽度（Ｔｇ）、信号周期（Ｔ）、时间常数（ＲＣ）和信噪比改善的关系，并在实际电路中进行了检测。
In this paper,we introduce the design of gate-integrator for collecting weak signals in dynamic equilibrium instrament.We also discusse the relation among the pulse-width (T g) of gate pulse,the period (T) of signal,the time constant (Rc) and the improvement of signal-noise-ratio.It is detected in the practical circuit.
