What are the inputs in a NOR gate to have an output of 1?
a The NOR gate. When either input is a logic 1, the output will be 0. The only combination of inputs that results in an output of 1 is A = 0 and B = 0.
Can a NOR gate have one input?
An AND gate gives a 1 output when both inputs are 1. Therefore, an AND gate is made by inverting the inputs of a NOR gate. Again, note that a NOT gate is equivalent to a NOR with its inputs joined….AND.
| Input A | Input B | Output Q |
|---|---|---|
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
What is a two input NOR gate?
The NOR gate is a digital logic gate that implements logical NOR – it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results. NOR is the result of the negation of the OR operator.
Do 2-input NOR gates form a complete set of logic gates?
Similarly cascading an OR and NOT gate together will produce a NOR gate, and so on. However, the two functions of AND and OR on their own do not form a complete logic set.
How many 2 input NOR gates required to construct a 2 input AND gate?
Similarly, the number of 2-input NOR gates required to implement a 2-input XNOR gate is 4.
Can and gate have 3 inputs?
Like the AND gate, the OR function can have any number of individual inputs. However, commercial available OR gates are available in 2, 3, or 4 inputs types. Additional inputs will require gates to be cascaded together for example.
How many 2-input NOR gates required to construct a 2-input AND gate?
Which gate will give an output of 1 when both its input is 1 or both inputs is 0 but gives an output of 0 when any of its input is different from the other?
An XOR gate is normally two inputs logic gate where the output is only logical 1 when only one input is logical 1. When both inputs are equal, either are 1 or both are 0, the output will be logical 0. This is the reason an XOR gate is also called an anti-coincidence gate or inequality detector.
What is the minimum number of 2 input NOR gates required?
3
Therefore, the minimum number of 2-input NOR gates needed to implement the function is 3.
What is truth table logic?
A truth table is a mathematical table used in logic—specifically in connection with Boolean algebra, boolean functions, and propositional calculus—which sets out the functional values of logical expressions on each of their functional arguments, that is, for each combination of values taken by their logical variables ( Enderton , 2001).
What is NOR gate?
The NOR gate is a digital logic gate that implements logical NOR – it behaves according to the truth table to the right.
What is NOR gates?
NOR Gate. Definition – What does NOR Gate mean? A NOR gate is a type of logic gate that works on the principle of “neither this nor that.” This type of digital logic gate produces a high output only if two binary results are satisfied by a zero or low input.
