Which of the following is a desirable characteristic of an instrument ?
Correct answer: B. High fidelity
- A. High drift
- B. High fidelity
- C. High measuring lag
- D. Poor reproducibility
Explanation
High fidelity means an instrument reproduces the input signal accurately in magnitude and form, making it a desirable characteristic. High drift, large measuring lag, and poor reproducibility all reduce measurement quality.
