摘　　要：信号调理的实质就是通过电子器件的有机组合,对信号进行调节、变换和整理的过程.信号调理电路的具体实现应综合考虑数据采集的目的、现场环境及控制系统的算法设计等各种因素审慎为之.该文论述了不同情况下通用信号调理电路的具体实现方法,并应用传递函数及其框图刻画了调理电路中信号的流动及转换过程,且在此基础上得出了信号调理电路的有关特征参数.The essential of signal conditioning is a transform process by electronic components. The design of signal conditioning circuit is related with the goal of data acquisition, field environment, real-time demands and algorithm of the control system as well as PC performance etc. Different methods of the general signal conditioning circuit are discussed. The transfer function and signal flow diagrams are used for description of the signal transform in the signal conditioning circuit and characteristic parameters of signal conditioning circuits are ealculated.
