MCQ
In a negative logic the following wave form corresponds to the
- A$0000000000$
- B$101101000$
- C$1111111111$
- ✓$1010010111$
✓
Answer
Correct option: D.
$1010010111$
d
(d)$5$ volt is low signal $(0)$ and $10$ volt is high signal $(1)$ and taking $5$ $\mu-sec$ as $1$ unit. In a negative logic, low signal $(0)$ gives high output $(1)$ and high signal $(1)$ gives low output $(0)$. The output is therefore $1010010111.$
