Data Acquisition Systems. Data acquisition is the process of sampling signals that measure real world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer.
Sense physical variables (use of transducers)
Condition the electrical signal to make it readable by an A/D board.
Convert the signal into a digital format acceptable by a computer
Process, analyze, store, and display the acquired data with the help of softwareContd. Data Acquisition System
Sense physical phenomena and translate it into electric signal.
Functions: modify the analog signal to match the performance of the ADC
Pre-filtering: remove undesirable high frequency components
Amplification: amplify the signal to match the dynamic range of the ADCSignal Conditioning
Transforms the PC and DAQ hardware into a complete DAQ, analysis, and display system.
