Implementation of Signal Sampling with FPGA

A high-speed sampling unit hardware realization based on FPGA is proposed,including the circuit design of data acquisition;the approach of high speed data transmission;the design of operational processor system and bus control system,and the VHDL program framework.The signal types are transformed by the sampler and then processed and stored with programmable gate arrays FPGA.Finally,the data of the sample unit is transmitted under the control of the whole system.
