一、前言在遥测技术应用中,信号的调整可以作为一项独立的条件或多路传输和传送系统的一个部分来考虑。在作为独立条件时,信号调整可以采用更为一般的方案。以便与电路的功能连系时有更大的灵活性。对于单个或多个元件的电阻传感器惯用的调整电路为图1(略)的惠斯登电桥电压激励。当传感器的元件少于四个 I. INTRODUCTION In telemetry applications, signal conditioning can be considered as an independent condition or as part of a multiplex transmission and transmission system. As a stand-alone condition, signal conditioning can be more generalized. In order to be more flexible in connection with the function of the circuit. The usual tuning circuit for a single or multiple element resistive sensor is the Wheatstone bridge voltage excitation shown in Figure 1 (omitted). When there are fewer than four sensor elements
