Decimated Filters for Acquisition System of Signs Electroencephalography
In digital electroencephalography, a sampling frequency of 200 samples per second (s.p.s) is theminimum used.

| description | In digital electroencephalography, a sampling frequency of 200 samples per second (s.p.s) is theminimum used. However, the present trend of these systems for recording brain electrical activity(EEG), in the area of research is the use of higher sampling at 1000 s.p.s, in order to reproduce shortevents (intracortical records epileptic activity) as well as to faithfully reproduce some kinds of artifactsto subtract digital post-processing means. Because this results in greater use of memory for thestorage of the data, in long records, as sleep studies, it is convenient to work with the minimumsampling frequency recommended by the IFCN (200m.ps) being necessary to lower it by a process ofdecimation. This paper presents the study and analysis of criteria for the design optimization ofdecimates stages for electroencephalographic signal implemented by a FIR digital filter, with a versatileapplication to EEG recording systems in development by the Neuroscience Center of Cuba (CNEURO) |
