Abstract :
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.
