One input of a NAND gate is low (logic level 0) and the other input is high (logic level 1).
The output state is?
1
0
The two inputs of a NAND gate are both low (logic level 0). The output state is...
1
0
symbol for a NAND gate is....
What gate is this truth table for?
AND
NOT
OR
THE
Which truth table is this?
XOR
NOR
NAND
NOT
Which are the UNIVERSAL GATES?
XOR Gate & NOT Gate
AND Gate & OR Gate
NAND Gate & NOR Gate
All of the above
In the case of OR gate,no matter what the no. of inputs a
1 at any input causes the output to be at logic 1
1 at any input causes the output to be at logic 0
0 any input causes the output to be at logic 0
0 at any input causes the output to be at logic 1.
The NOR Gate is OR Gate followed by ...............
OR Gate
NOT Gate
AND Gate
None of the above
NAND Gate is called a universal logic element, because
It is used by everybody
Any logic function can be realised by NAND Gate alone
Many digital computers use NAND Gate
All the minimisation techniques are applicable to optimum NAND Gate realisation
