Question

The following figure shows a logic gate circuit with two inputs A and B and the output Y. The voltage waveforms of A, B and Y are givenThe logic gate is :(a) NAND gate(b) NOR gate(c) OR gate(d) AND gate

Answer 1

I think the answer is NAND gate

Answer 2

Answer:

A) NAND gate

Explanation:

Inputs of the logic gate circuit = A and B ( Given)

Voltage wave forms given -

NAND gate - NOT + AND gate

- wherein

Y= A.B

where A and B are input and Y is output

Thus, the truth table corresponding to waves  A B and Y formed will be

A B Y

1 1 0

0 0 1

0 1 1

1 0 1

This represents NAND gate

.

Thus, the voltage wave forms of A, B and Y are given by the logic gate NAND gate
