A 10 bit A/D convertor is used to digitize an analog signal in the 0 to 5 V range. The maximum peak to peak ripple voltage that can be allowed in the d.c. supply voltage is—
-
- nearly 100 mV
- nearly 50 mV
- nearly 25 mV
- nearly 5 mV
Correct Option: D
| Smallest incremental change = | = | ||
| 210 | 1024 |
For 5V,
| = nearly 5 mV | |
| 1024 |
Hence alternative (D) is the correct answer.
