Digital filtering through a certain calculation orprogram determination to reducing the proportion of noise interference superimposingon the useful signal, so as to improve the quality of signal acquisition. Thedigital filtering is realized by program and does not need additional hardware，anddifferent filtering methods or filtering parameters can be used according todifferent signal, so it has good stability, strong function. Digital filteringhas stronger capacity in inhibiting the interference from low frequency signal.
