Firstly,the method that makes potentiometer far from the input terminal of amplifier and puts the potentiometer on the side of big signal can decrease the effect of noise voltage on whole circuit to a certain extent.
其中 ,使电位器的滑动接点远离放大器的输入端及尽可能将电位器用在大信号一侧的方法 ,能在一定程度上减小噪声电压对整个电路的影响 ;在继电器线圈两端并接高速放电二极管和 RC吸收电路能大大消弱继电器工作时线圈两端产生的负脉冲电压 ;用金属壳将高输入阻抗放大器的输入端屏蔽可消除各种外界干扰信号对放大器的干扰 ,而在高输入阻抗放大器的输入端接入隔离环可减少电源线漏电等对放大器的影响 ;在数字电路的终端连接终端电阻会明显改善数字电路中易出现的终端反射效
