Download Solution PDFConcept:
The resolution of a Digital-to-Analog (D/A) converter is the smallest change in analog output corresponding to a one-bit change in the digital input.
It is given by: \( \text{Resolution} = \frac{V_{max}}{2^n - 1} \)
Where,
- \( V_{max} \) is the maximum output voltage
- n is the number of bits
Given:
Number of bits, n =9
Maximum output voltage, \( V_{max} = 5.12 \, V \)
Calculation:
\( \text{Resolution} = \frac{5.12}{2^9 - 1} = \frac{5.12}{511} \approx 0.01 \, V = 10 \, mV \)
Correct Answer: 1) 10 mV
