WHEN AND gate output is high?
The AND gate is a basic digital logic gate that implements logical conjunction (∧) from mathematical logic – it behaves according to the truth table above. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If none or not all inputs to the AND gate are HIGH, LOW output results.
Which gate gives high output?
EOR gate. The Exclusive-OR gate is a circuit which gives a high output if either of its two inputs is high, but not both. A encircled plus sign ( ) is used to indicate the EOR operation.
Which gate has the high output only when both the inputs are high?
XNOR gate
3) The output is high when both the inputs are the same. 4) XNOR gate produces an output only when the two inputs are same….Detailed Solution.
| Input A | Input B | Output Y = A ⊕ B ― |
|---|---|---|
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
Which logic function has the output high only when all inputs are high?
NAND gate
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.
How many and gates are required to realize?
How many AND gates are required to realize Y = CD + EF + G? Explanation: To realize Y = CD + EF + G, two AND gates are required and two OR gates are required.
Why NAND gate is a universal gate?
Thus, the NAND gate is a universal gate since it can implement the AND, OR and NOT functions. NAND Gate is a Universal Gate: To prove that any Boolean function can be implemented using only NOR gates, we will show that the AND, OR, and NOT operations can be performed using only these gates.
When does the output of a gate go high?
whose output HIGH only when all the inputs are 1 (HIGH) otherwise the output will be LOW. OR Gate: The Logic OR Gate is a digital logic circuit whose output goes HIGH only when any one or more than one of its inputs is HIGH.
What happens when both inputs are high or low?
However, when both inputs are “high” (1), the NAND gate outputs a “low” (0) logic level, which forces the final AND gate to produce a “low” (0) output. Another equivalent circuit for the Exclusive-OR gate uses a strategy of two AND gates with inverters, set up to generate “high” (1) outputs for input conditions 01 and 10.
What happens when the and GATE input is low?
When the AND gate enable input is low, the output will remain a constant low signal. A two input OR gate can also be used with one input the desired signal and the other input is the enable. The enable input of an OR gate is low active. This means that the output will be a copy of the input signal when the enable is low.
Can a gate be made with more than two inputs?
NOR gates, like all the other multiple-input gates seen thus far, can be manufactured with more than two inputs. Still, the same logical principle applies: the output goes “low” (0) if any of the inputs are made “high” (1). The output is “high” (1) only when all inputs are “low” (0).
