Show answer and explanation
Correct answer: 0.24 to 0.26
Explanation
The8Vrange is divided into16equal intervals, giving step size Δ=8/16=0.5V. With nearest-level reconstruction the largest magnitude of quantization error is half a step, Δ/2=**0.25V**. This is an error bound rather than an rms noise value.
