数字显示系统中模拟信号前置放大的干扰分析

Interference Analysis on the Preamplification of the Anologue Signals in Digital Display System

为避免各种干扰对模拟-数字显示仪表测量结果的影响,从显示原理的角度出发对横向、纵向以及显示仪器内部的干扰源的来源进行了分析,重点论述了横向干扰信号的抑制措施,特别是从信号转换原理上对干扰的抑制措施.

In order tO avoid the effect of interference on the metering results of analogue-digital displaying instruments, this paper analyzes the horizontal and vertical interference sources and interference source inside the displaying instruments in terms of displaying principles, emphatically discusses the restraining measures against horizontal interference, especially in terms of principles of signal conversion.
