Question

if input is equal to 1 and b is equal to 1 what is the output of n o r - gate​

Answer 1

Answer:

The inclusive NOR (Not-OR) gate has an output that is normally at logic level “1” and only goes “LOW” to logic level “0” when ANY of its inputs are at logic level “1”. The Logic NOR Gate is the reverse or “Complementary” form of the inclusive OR gate we have seen previously.

Logic NOR Gate Equivalent

2-input nor gate equivalent

The logic or Boolean expression given for a logic NOR gate is that for Logical Multiplication which it performs on the complements of the inputs. The Boolean expression for a logic NOR gate is denoted by a plus sign, ( + ) with a line or Overline, ( ‾‾ ) over the expression to signify the NOT or logical negation of the NOR gate giving us the Boolean expression of: A+B = Q.

Then we can define the operation of a 2-input digital logic NOR gate as being:

“If both A and B are NOT true, then Q is true”
