What is a data acquisition card?
Data acquisition (DAQ) is the process of measuring events based on voltage, current, pressure, temperature, or sound. A DAQ system consists of high-speed data acquisition measurement hardware (DAQ cards or modules), input devices such as sensors, and a computer or processor.
What is an FPGA for data acquisition?
As the core of the data acquisition system, FPGA collects and stores data. The system is divided into three modules: front-end signal processing module, FPGA data acquisition module and data storage module. The FPGA data acquisition module is designed with VHDL and simulated by ISE software.
