2.4. What are the differences between analogue and digital instruments? What advantages do digital instruments have over analogue ones?
Solution
Advantages of digital over analog instruments:
1) They are very easy to read.
2) Since there are very few moving parts in the electronic instruments, they are usually more accurate than theanalogue instruments. Even the human error involved in reading these instruments is very less, which adds to the accuracy of digital instruments.
3) The electronic items tend to be cheaper than the mechanical items.
4) The data from the instruments can be recorded for future reference.
5) The output of the digital devices can be obtained in the computer
| ANALOG INSTRUMENTS | DIGITAL INSTRUMENTS |
| 1.Signals in continuous fashion,gives infinite no of values in given period | It gives finite values in given period of time |
| 2.These occupy more space | occupies less space |
| 3.Accuracy is poor | Accuracy is good |
| 4.Chance of parallox error | no such problem |
| 5.More chances of error due to operator | very less |
| 6.Not effects with temperature | These are effected by temperature |
