Give two ways of converting a two input NAND gate to an inverter.
Answer:
One way is shorting the two inputs of the NAND gate and passing the input.
truth table:
A B output
1 1 0
0 0 1
The second way is passing the input to only one input(say A) of the NAND gate.Since the other input(say B) is floating, it is always logic one.
truth table:
A B output
1 1 0
0 1 1
