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