Abstract

Data acquisition system is widely used in modern technology. This paper designs a high-speed digital acquisition system based on FPGA. In the design, the FPGA is the core of the control system, control of high speed ADC sampling data, and combining the Altera company’s FIR low-pass filtering IP check out data, and convert the data throw the FIFO, and the data stored in a dynamic memory SDRAM, and turn the USB serial port circuit transmission to the computer display and data analysis. The reliability of the system was verified by MATLAB processing.
