## How many gates are used in multiplexer?

From the above expression of the output, a 4-to-1 multiplexer can be implemented by using basic logic gates. The below figure shows the logic circuit of 4:1 MUX which is implemented by four 3-inputs AND gates, two 1-input NOT gates, and one 4-inputs OR gate.

How many and gates are required for a 8 to 1 multiplexer?

8 AND gates
For a 1 to 8 multiplexer a total of 8 AND gates are required.

### How many and gates are required for a 1 to 8 multiplexer A 2 B 6 C 4 D 5?

How many AND gates are required for a 1-to-8 multiplexer? Explanation: The number of AND gates required will be equal to the number of outputs in a demultiplexer, which are 8.

How many and gates are required for 1 to 4 demultiplexer?

From the above Boolean expressions, a 1-to-4 demultiplexer can be implemented by using four 3-input AND gates and two NOT gates as shown in figure below. The two select lines enable a particular AND gate at a time.

## What is a MUX gate?

Multiplexers, or MUX’s, can be either digital circuits made from high speed logic gates used to switch digital or binary data or they can be analogue types using transistors, MOSFET’s or relays to switch one of the voltage or current inputs through to a single output.

Which gate is not used in multiplexer?

Multiplexer can act as universal combinational circuit. All the standard logic gates can be implemented with multiplexers. It is NOT Gate using 2:1 MUX. The implementation of NOT gate is done using “n” selection lines.

### How many lines will a 64 to 1 multiplexer have?

Using the above formula, we can obtain the same. Hence, total number of 4 : 1 MUX are required to implement 64 : 1 MUX = 16 + 4 + 1 = 21.

What is multiplexer circuit?

In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. The selection is directed by a separate set of digital inputs known as select lines.

## Which gate is not required to implement a multiplexer?

NOT Gate : The implementation of NOT gate is done using “n” selection lines. It cannot be implemented using “n-1” selection lines.

What is multiplex circuit?

The multiplexer, shortened to “MUX” or “MPX”, is a combinational logic circuit designed to switch one of several input lines through to a single common output line by the application of a control signal.

### Which of the following logic gate can be implemented by using 2 1 multiplexer?

Answer: Implementation of NAND, NOR, XOR and XNOR gates requires two 2:1 Mux. First multiplexer will act as NOT gate which will provide complemented input to the second multiplexer.

How many signals will be there in 32 1 MUX?

For 32 inputs, 5 select lines will be required, as 25 = 32.

## How do you implement and gate using MUX?

c) Implementation of OR gate using 2 : 1 Mux using “n-1” selection lines. Implementation of NAND, NOR, XOR and XNOR gates requires two 2:1 Mux. First multiplexer will act as NOT gate which will provide complemented input to the second multiplexer. Three(3) ​2 : 1 MUX are required to implement 4 : 1 MUX.

Which gates are used in multiplexer?

### What are the basic logic gates?

The logic of this gate is that the output would be 1 when at least one of the inputs is 1.

• If there are two inputs A and B,then the OR gate’s output will be given by the following mathematical operation: Y = A+B
• The symbol and truth table for an OR gate can be given as:
• What are the uses of logic gates?

– Logic Gates. A logic gate is a simple switching circuit that determines whether an input pulse can pass through to the output in digital circuits. – Boolean Algebra. – Types of Logic Gates. – Basic Logic Gates. – Universal Logic Gates. – Other Logic Gates. – Uses of Logic Gates. – Sample Questions.

## What are the types of logic gates?

Or-gate. Or gate has two and more inputs terminal but we get only one output terminal.

• And-gate. And gate has two and more inputs terminal but we get only one output terminal.
• Not-gate: In not gate only one input and one output.
• Nand-gate: Nand gate is a combinational logic gate is constructed with not gate and and gate (not+and).
• What is logic gates in computer with example?

In this article, I explain What is logic Gates in Computer, and the type of logic gates with an Example. What is logic Gates in Computer? A Logic gate performs a logical operation on one or more logic inputs and produces a single logic output. However, In this logic normally use is Boolean logic, and that is most commonly found in digital circuits. So Logic gates are primarily implemented electronically using diodes or transistors.
