Acquisition system and approximation of brain signals
José de Jesús Rubio, Diana M. Vázquez, Dante Mújica‐Vargas · IET Science Measurement & Technology · 2013
In this study, one acquisition system of one channel is introduced to obtain the biological brain signals. Such system consists of a low‐pass filter, an amplifier, a high‐pass filter and a data acquisition board. A novel slopes algorithm with guaranteed bounded output is proposed for the approximation of the brain signals. The proposed method is compared with both the least‐squares and nearest‐neighbour algorithms.
