Design of Data Acquisition System Based on USB 2.0 Technique

For a faster and more accurate demand for data acquisition in current engineering projects,a new simultaneous multiple data acquisition system is designed.It can acquire simultanceous multiple data and communicate with computers by using USB 2.0 interface chip CY7C68013A and AD7658.The experimental results support the characteristics of the system are steady work,transmission with high speed and it satifies the demand of elementary design.Conclusion is that the method is viable,its characteristics are stimultaneous,high speed and simple circuit,it is a meathod of data acquisition that can be extended.
