Design of data acquisition system based on FPGA and USB

This paper introduced the data acquisition system using in the precision measurement of the muzzle blast.The acquisition system based on universal serial bus(USB) and Field Programmable Gate Array(FPGA).FPGA control the whole system of collecting time-series,USB chip act as a data acquisition channel,and PC completes data display.Finally,environment testing for the system is carried on,and the comparison and analyses are made in terms of experiment results.
