What is the output of an OR gate if the inputs are 1 and 0?
The output of the circuit will be the opposite of the input. If 0 is input, then the output is 1. If 1 is input, then 0 is output….NOT gate.
| A | Q |
|---|---|
| 1 | 0 |
| 0 | 1 |
Is a circuit with only one output but can have multiple inputs?
Explanation: A logic gate is used to evaluate a Boolean expression. It can have multiple inputs but can have only one output. A NAND gate as well as the NOR gate can be used to implement any other Boolean expression thus it is called as a universal gate.
Which gate is used to reverse the output?
Inverter
Can an 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.
Can a logic gate have more than 2 inputs?
As with AND gates, NAND gates are made with more than two inputs. In such cases, the same general principle applies: the output will be “low” (0) if and only if all inputs are “high” (1). If any input is “low” (0), the output will go “high” (1).
Which is not a logic gate?
A NOT gate, often called an inverter, is a nice digital logic gate to start with because it has only a single input with simple behavior. A NOT gate performs logical negation on its input. In other words, if the input is true, then the output will be false.
What is the maximum number of inputs a logic gate can have?
Digital logic gates can have more than one input, for example, inputs A, B, C, D etc., but generally only have one digital output, (Q).
How many inputs signals can a gate have?
Inputs and outputs Gates have two or more inputs, except a NOT gate which has only one input. All gates have only one output.
When the inputs to a 3 input AND gate are 001 the output is 1?
When the inputs to a 3-input OR gate are 001, the output is 1. An application requires a 3-input AND gate; however, all three of the inputs actually produce a LOW when the inputs are ON.
How many and gates are required for a 8 to 1 multiplexer?
8 AND gates
How many two input AND gates and two input OR gates are required to realize?
How many two input AND gates and two input OR gates are required to realize Y = BD + CE + AB? Explanation: There are three product terms. So, three AND gates of two inputs are required.
Which one of the below mentioned logic gates gives 0 as output when two inputs are same?
From the above shown logic tables, we can say that for NAND and NOR gate, we will get the output ‘0’ when both the inputs are 1.
Which logic gates are universal?
A universal gate is a gate which can implement any Boolean function without need to use any other gate type. The NAND and NOR gates are universal gates. In practice, this is advantageous since NAND and NOR gates are economical and easier to fabricate and are the basic gates used in all IC digital logic families.
How many different sets of input conditions will produce a low output from a five input AND gate?
How many different sets of input conditions will produce a HIGH output from a five-input OR gate? Sol. The total number of sets of input conditions are 25 = 32. The output is low only when all the inputs are low.
How many 2 input NOR gates does it take to produce a 2 input NAND gate?
Now, 4 gates are essential to form NAND gates. For Input: For input it is important to have 2 NOR gates. These should be single inputs for input.
Which logic function provides a low output in response to one or more low inputs?
The unique output of the NAND function is a low output only when all inputs are low. Manufacturers’ data manuals include traditional logic symbols and are recently including the newer IEEE functional logic symbols.
When a 1 is on the input of an inverter What is the output?
The output of an inverter is the complement (opposite) of the input. When the input to an inverter is high (1) the output is low (0); and when the input is low, the output is high. In Boolean Algebra the inverter operation is shown by placing a bar over the variable.
WHY IS NOT gate called an inverter?
A NOT gate puts the input condition in the opposite order, means for high input it give low output and for low input it give high output. For this reason NOT gate is known as inverter circuit.
WHAT IS AND OR invert gate?
AND-OR-Invert (AOI) logic and AOI gates are two-level compound (or complex) logic functions constructed from the combination of one or more AND gates followed by a NOR gate. The complement of AOI Logic is OR-AND-Invert (OAI) logic where the OR gates precede a NAND gate.
Why XOR gate is called an inverter?
Why XOR gate is called an inverter? Explanation: The XOR (Exclusive Or) gate has a true output when the two inputs are different. When one input is true, the output is the inversion of the other. When one input is false, the output is the non-inversion of the other.
Why is it called an AND gate?
Basic logic gates The AND gate is so named because, if 0 is called “false” and 1 is called “true,” the gate acts in the same way as the logical “and” operator. The output is “true” when both inputs are “true.” Otherwise, the output is “false.” In other words, the output is 1 only when both inputs one AND two are 1.
Is XOR a universal gate?
2 Answers. You can’t derive an OR (or AND, NOR, NAND) gate from only XOR (or XNOR) gates, because they are not universal gates. Here is an argument against XOR and XNOR as universal gates. An XNOR gate is an XOR followed by an inverter, so it is also a parity generator.
How many NAND gates are required to make an AND gate?
2 NAND
What is the difference between NAND and NOR gate?
NOR circuit basics. A NAND gate is conceptually implemented as an AND gate — output 1 when both inputs are 1 — followed by a NOT gate, which is a logical inversion. Likewise, a NOR gate is conceptually an OR gate — output 1 when either input is 1 followed by the NOT gate, which is a logical inversion.
What is the symbol of not gate?
The standard NOT gate is given a symbol whose shape is of a triangle pointing to the right with a circle at its end. This circle is known as an “inversion bubble” and is used in NOT, NAND and NOR symbols at their output to represent the logical operation of the NOT function.
How do you make a NAND NOT gate?
A NOT gate is made by joining the inputs of a NAND gate together. Since a NAND gate is equivalent to an AND gate followed by a NOT gate, joining the inputs of a NAND gate leaves only the NOT gate.
