前言随着电子计算机应用技术的推广和集成电路的普及,数字化的电子测量技术已是发展趋势,为此,就需对非线性的温度传感器进行线性化处理,目前已有的多种线性化方法各有其特点,本文所探讨的线性化方法是:在已知热电偶特性曲线后(或相应的数值表),通过多项式逼近函数的方法来建立一个函数发生器电路,该电路的传输特性恰为热电偶的反函数,它将由模拟相乘器和 Preface With the popularization of the application of computer technology and the popularization of integrated circuits, digital electronic measurement technology is the development trend. Therefore, it is necessary to linearize the nonlinear temperature sensor. Currently, a number of linearization methods Each has its own characteristics. The linearization method discussed in this paper is to establish a function generator circuit by polynomial approximation function after known thermocouple characteristic curve (or corresponding numerical value table), the transmission characteristic of this circuit is just For the thermocouple inverse function, it will be simulated by multipliers and
