许多场合广泛存在着把非线性曲线线性化的问题。通常的办法是增加一个或几个特定的非线性元件,应用叠加原理加以合成,使被测物理量与校正后的输出信号间,近似地成为线性关系,或者人为地制作一个模拟函数发生器,把非线性曲线线性化,但这些办法都比较粗糙。 在已经使用了电子计算机的场合,可用计算机进行插补校正。但在许多场合,没有计算机,而且,也不一定非用计算机不可。本文设想通过模拟运算,将非线性特性曲线线性化。 如图1所示,V实=f(T)是传感器的实际输出曲 In many cases there is a widespread problem of linearizing nonlinear curves. The usual method is to add one or more specific nonlinear elements and apply the superposition principle to make the measured physical quantity and the corrected output signal approximately linearly related or to make an analog function generator artificially Nonlinear curve linearization, but these methods are relatively rough. Where an electronic computer has been used, a computer can be used for interpolation correction. But on many occasions, there is no computer, and not necessarily a computer. This article envisions linearizing the non-linear characteristic curve through simulation. As shown in Figure 1, V = f (T) is the actual output of the sensor
