Depression of Drift Noise in Sensor with a Discrete Change Variable Through Detachment of Signals
Wen Yu · Dianzi xuebao · 1999
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.
