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 as given.
The logic gate is
A
NOR gate
B
OR gate
C
AND gate
D
NAND gete
Answer
NAND gete
Explanation
Solution
: it is clear from the given logic circuit, that the output Y is low when both the inputs are high, otherwise it is high. Thus logic circuit is NAND gate.
| A | B | Y | ||||||
|---|---|---|---|---|---|---|---|---|
| 1 | 1 | 0 | ||||||
| 0 | 0 | 1 | ||||||
| 0 | 1 | 1 | ||||||
| 1 | 0 | 1 | ||||||
