21.
TTL logic is preferred to DRL logic because
greater fan-out is possible
greater logic levels are possible
greater fan-in is possible
less power consumption is achieve
Answer: Option
Explanation:
No answer description is available. Let's discuss.
22.

Assertion (A): Schottky transistors are preferred over normal transistors in digital circuits

Reason (R): A Schottky transistor when used as a switch, between cutoff and active region.

Both A and R are correct and R is correct explanation of A
Both A and R are correct but R is not correct explanation of A
A is true, R is false
A is false, R is true
Answer: Option
Explanation:

Schottky transistors are fast switching because saturation is avoided.

23.
The inputs A and B of the given figure are applied to a two input NOR gate. The output waveform is
Answer: Option
Explanation:
No answer description is available. Let's discuss.
24.
In the circuit of the given figure, V0 =
5 V
3.1 V
2.5 V
0
Answer: Option
Explanation:

Transistor is off and circuit current is zero.

25.
A parallel in-parallel out shift register can be used to introduce delay in digital circuits.
True
False
Answer: Option
Explanation:

No time delay in this shift register since all bits are loaded and read simultaneously.
