The resolution of D/A converter is approximately 0.4% of its full-scale range. It is
- A. An 8-bit converter
- B. A 10-bit converter
- C. A 12 bit converter
- D. A 16 bit converter
Answer: A. An 8-bit converter
Explanation: The resolution of a D/A converter as a percentage is given by (1 / (2^n - 1)) * 100% or approximately (1 / 2^n) * 100%. For an 8-bit converter, 1 / 2^8 = 1 / 256 = 0.0039, which is approximately 0.39% or 0.4%.
