| Abstract: | The paper discusses an apparatus' design and development, which can sample and process the electric signal of the creature concerning pic micro cont roller. Eliciting the electric signal through an electrode then amplified and tr ansferred it into digital signal which is controlled intelligently by PIC microp rocessor. This apparatus has the function of acquiring amplifying and processing the micro signal of the creatures, and could be offered power singly. Compared with its same series products, this facility has higher immunity and operated si mply. It can be used in medical experiments of colleges and institutions. |
