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
