| Abstract: | This paper is about the design and implement of the data acquisition system which includes four channels and convenient to use. Associated with the firmware and application software the system can sample the analog signal and then transform it into digital signal, at last these data saved to the PC, through data transform such as filter, FT, differential and integral calculus we get the final data result. |
