| Abstract: | Based on a new intelligent DECG signal collecting and analyzer,this paper deals with the related noise attenuation and data filtering problem. Hardware structure and characteristic of the instrument is given, and the designing method and data filtering algorithm of the 50Hz industrial wave filter and baseline shifted filter are analyzed in detail, in the meantime it describes the interpretation of the digital compression and memory methods for DECG signals, which could highly increase the signal processing speed and analyzing accuracy. The experiment wave and data processing result show the efficiency of our proposed methods. |
