摘要
运用传感器的静态标定值,拟合信号调理器的传输函数,使由传感器和信号调理器共同组成的传感器通道的传输函数为线性函数。针对这种情况,论述并证明了用全最小二乘法比用最小二乘法能获得更高的拟合精度。
To make the transition function of a sensor channel linear the sensor’s static marks is usually used to fit the transition function of the signal compromise circuit. The total least square method has more fitting precision than the least square one.
