Output is LOW if and only if all the inputs are HIGH'. Indicate the logic gate for which the above statement in ture :-

What is logic gate with one input and one output?

If the output is high for anyone of all of the inputs then it is ……… gate .

It is required to design a (two -input) logic gate, using an appropriate number, of : (a) NAND gates that gives a 'low' output only when both the inputs are 'low'. (b) NOR gates that gives a 'high' output only when both the inputs are 'high'. Draw the logic circuits for these two cases and write the truth table, corresponding to each of the two designs.

The output of 2 input gate is 1 only if its inputs are equal. It is true for :-

The output A when all three inputs are first high and then low respectively, be

The gate for which output is high, if atleast one input low is
