By using an eight bit optical encoder the degree of resolution that can be obtained is (approximately)
- A.
1.8o
- B.
3.4o
- C.
2.8o
- D.
1.4o

Show answer & explanation
Correct answer: D
The resolution of an n-bit optical encoder is determined by the formula 360° / 2ⁿ. For an eight-bit encoder, n = 8, so the total number of positions is 2⁸ = 256. Dividing 360° by 256 gives approximately 1.406°, which corresponds to the correct option.
