Which logic gate produces 0 when all inputs are high or 1?
In digital electronics, 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.
Which gate have Output 1 when both input is zero?
NOR gate
NAND gate – output is 1 if AT LEAST one input is 0. NOR gate – output is 1 if BOTH inputs are 0.
What is the output when the input value is 0?
When the inputs are 1 and 0 , the output is zero.
Is the output of a logic gate always the same?
The OUTPUT of a gate provides two nominal values of voltage only, e.g. 0V and 5V representing logic 0 and logic 1 respectively. In general, there is only one output to a logic gate except in some special cases. There is always a time delay between an input being applied and the output responding.
Which is the combination of and NOT gate?
This basic logic gate is the combination of AND and NOT gate. This gate is the combination of OR and NOT gate. In XOR gate the output of a two-input XOR gate attains the state 1 if one adds only input attains the state 1. A. B ˉ + A ˉ. B In XNOR gate the output is in state 1 when its both inputs are the same that is, both 0 or both 1.
When does the output of an OR gate attain the state?
I n OR gate the output of an OR gate attains the state 1 if one or more inputs attain the state 1. The Boolean expression of OR gate is Y = A + B, read as Y equals A ‘OR’ B. In AND gate the output of an AND gate attains the state 1 if and only if all the inputs are in state 1.
What is the uncertain range of a logic gate?
Within the “uncertain” range for any gate input, there will be some point of demarcation dividing the gate’s actual “low” input signal range from its actual “high” input signal range.
