Answer

Correct option: (ii) Extract meaningful insights

Explanation

Data processing converts raw acquired data into useful information that can be interpreted or used for decision-making.

Typical processing operations include:

• Data cleaning and removal of invalid values.
• Noise reduction and filtering.
• Calibration and scaling.
• Averaging and statistical calculations.
• Feature extraction.
• Conversion into engineering units.
• Preparation of data for visualization or control.

For example, raw vibration samples can be processed to calculate RMS vibration, peak amplitude or frequency components, helping identify a machine fault.

Therefore, the correct answer is (ii).
