The eeg signal registration and processing with the use of chebyshev polynoms

In physiological studies, for the evaluation of brain activity, an important condition is the removal of the electroencephalogram. The article deals with the construction of a computer system for registration of EEG using the interrupt mode at the level of structure and algorithmic support. Depending on the recording technique, the system contains from three to sixteen amplitude measuring channels. An additional procedure for digital filtration using the Chebyshev polynomials is proposed for filtering of high-frequency interferences. The calculations made showed its effectiveness. The method of estimation of the minimum length of realization is offered
