Digital Vs Analog Measurement
Hardphysics
Digital instruments reduce observational error mainly by:
Select the correct option:
Solution
Incorrect! Answer:
Displaying direct numerical value
Analog instruments require the observer to estimate the position of a needle between marks (interpolation) and are subject to parallax.
- Digital instruments perform internal A/D conversion and show a discrete number.
- This removes personal 'bias' and 'reading errors' from the observer, although the inherent electronic error of the device still exists.
