The gate whose output is low if and only if all inputs are high, is
Open in App
Solution
The correct option is A NAND
The gate whose output
is low if and only if all inputs are high, is NAND.
The logic NAND gate is a
combination of a digital logic AND gate and a NOT gate connected together in
series.
A NAND gate (NOT-AND) is a logic gate which
produces an output which is false only if all its inputs are true; thus its
output is complement to that of an AND gate. A LOW (0) output results only
if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1)
output results.
