What is the output if a NOR gate with one high input AND one low input?
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.
What is the output of an OR gate if the inputs are 1 AND 1?
Combinational circuits are built of five basic logic gates: AND gate – output is 1 if BOTH inputs are 1. OR gate – output is 1 if AT LEAST one input is 1. XOR gate – output is 1 if ONLY one input is 1.
When an input signal 1 is applied to a NOT gate the output is?
Hence for input signal \[1\] the output will be \[0\].
What is the output of an AND gate if the inputs are 1 AND 0?
If the input is 1, then the output is 0. If the input is 0, then the output is 1.
When the output of NOR gate is high?
Detailed Solution. The Output of NOR gate is high when all inputs are low.
What would be the output in XNOR gate when all the inputs are high?
The two-input version implements logical equality, behaving according to the truth table to the right, and hence the gate is sometimes called an “equivalence gate”. A high output (1) results if both of the inputs to the gate are the same. If one but not both inputs are high (1), a low output (0) results.
What is the output of OR gate?
1
An OR gate is a logical gate that has two or more inputs that can give an output of 1 which is called high or 0 which is called low. The output of an OR gate comes back low only when all the inputs attached to the OR gate have their value low. In all other situations, the output of the OR gate is one.
Which of the following operations produce a 1 if the input bits are 1 and 1?
OR gate
Explanation: An OR gate gives the result as 1 if any one of the inputs is one. Its expression is A+B.
When A and B are inputs output of OR gate is?
Detailed Solution. The output of AND gate is given as AB hence its value is logic 1 when both inputs A and B are logic 1’s.
How do you describe the actions of a logic gate?
The actions of any of these gates can also be described using Boolean statements. These use letters from the beginning of the alphabet, such as A, B, C etc. to indicate inputs, and letters from the second half of the alphabet, very commonly X or Y (and sometimes Q or P) to label an output.
What is the difference between and AND OR gate output?
The AND gate output is at logic 1 when, & only when all its inputs are at logic 1, otherwise the output is at logic 0. The OR gate output is ate logic 1 when one or more of its inputs are at logic 1. If all its inputs are at logic 1 , the output is at logic 0.
What is the binary output of a logic gate?
Depending on the type of logic gate being used and the combination of inputs, the binary output will differ. A logic gate can be thought of like a light switch, wherein one position the output is off — 0, and in another, it is on — 1. Logic gates are commonly used in integrated circuits (IC).
How do logic gates obey the truth table?
All logic gates obey their truth table. A NOT gate produces an output that is the complement of the input. It has only one input signal. It produces a 1 output when the input is 0. and It produces a 0 output when the input is 1. The four commonly used methods of expressing the NOT operation as shown in the figure.
