High-speed Information Acquisition and Processing Using FPGA

The received electromagnetic wave is converted to the electronic signal by the sensor, then the electronic signal is transformed into data flow by a high speed ADC for processing with the circuit composed of FPGA. The worked data is accumulated to the system computer for judging read and analysis. The system is applied mainly in the remote sensing information acquisition and processing. The system has 250MHz sampling rate and USB2.0 bus, so it also can be applied in other information acquisition fields.
