By using an eight-bit optical encoder the degree of resolution that can be obtained is (approximately)
|
1.8o
|
|
|
3.4o
|
|
|
2.8o

Question 12 Explanation:
An optical encoder is an electromechanical device which has an electrical output in digital form proportional to the angular position of the input shaft.
Optical encoders enable an angular displacement to be converted directly into a digital form.
Encoder resolution is often referred to in bits, which are binary units: a 16 bit resolution rotary encoder will have 65,536 (216) increments per turn, or PPR.
In the given question, 8-bit optical encoder will have 28 increments
Resolution = 360/2n = 360/28 = 1.4o
