摘要 在传感器的输出信号中,漂移噪声是一阶或一阶以上连续的,而在有的传感器中,传感量的变化在时间轴上是离散的.正是基于这两个显然不同的信号特征,本文提出在这类传感器中,利用输出采样的差分值,从传感器输出中将传感信号和漂移信号分离.不采用任何其它的漂移变量补偿元件和电路,可以消除零点漂移。 Usually drift signal has a first order continuity while sensing variable has a discrete change in some sensors.According to the different characteristics between drift signal and discrete change sensing signal,the difference of output samples are used to detach sensing signal from sensing output mixed with drift signal.It cancels the drift without any compensation devices.
