## What is multiplexer explain 4×1 multiplexer?

4×1 Multiplexer has four data inputs I3, I2, I1 & I0, two selection lines s1 & s0 and one output Y. One of these 4 inputs will be connected to the output based on the combination of inputs present at these two selection lines. Truth table of 4×1 Multiplexer is shown below.

## What is a multiplexer explain the logic diagram and working of 4/1 multiplexer in detail?

4 to 1 Multiplexer A 4-to-1 multiplexer is a digital multiplexer that has four data inputs, two select lines, and one output. To implement a 4-to-1 multiplexer circuit we need 4 AND gates, an OR gate, and a 2 NOT gate.

**How do you make a 4 1 multiplexer?**

Here are the steps to design or construct 4 to 1 Multiplexer or 4:1 MUX using Logic Gates : 1) Now, make a diagram of multiplexer with 4 input lines, 2 selection lines and 1 output. In below diagram, A0 , A1 , A2 and A3 are input data lines, S0 and S1 are Selection lines and lastly one output line named Y.

### How many numbers are in a 4 to 1 MUX output?

In 4:1 MUX, there will be 4 input lines and 1 output line. And to control which input should be selected out of these 4, we need 2 selection lines.

### How many and gates are required for the construction of a 4 to 1 multiplexer?

12. How many NOT gates are required for the construction of a 4-to-1 multiplexer? Explanation: There are two NOT gates required for the construction of 4-to-1 multiplexer. x0, x1, x2 and x3 are the inputs and C1 and C0 are the select lines and M is the output.

**What is the number of data input in 4 1 multiplexer Mcq?**

Explanation: There are two NOT gates required for the construction of 4-to-1 multiplexer. x0, x1, x2 and x3 are the inputs and C1 and C0 are the select lines and M is the output. Explanation: The output will be X1, because c1 = 0 and c0 = 1 results into 1 which further results as X1.

## How many 4 to 1 multiplexers are required for the construction of a 16 to 1 multiplexer?

A 16 × 1 multiplexer has 16 inputs so if we use 4 × 1 multiplexers: At first stage: 4 multiplexers are needed for 16 inputs, At second stage: the output of these 4 multiplexers is connected to inputs of 1 multiplexer. Total 4 × 1 multiplexers needed are 4 + 1 = 5.

## How many OR gates are required for the construction of a 4 to 1 multiplexer?

Explanation: There are two NOT gates required for the construction of 4-to-1 multiplexer.

### How may inverters are needed to implement 4 1 multiplexer 1 marks?

Three(3) 2 : 1 MUX are required to implement 4 : 1 MUX.

### What are multiplexers in digital logic?

Multiplexers in Digital Logic. It is a combinational circuit which have many data inputs and single output depending on control or select inputs. For N input lines, log n (base2) selection lines, or we can say that for 2 n input lines, n selection lines are required. Multiplexers are also known as “Data n selector, parallel to serial

**What is multiplexer in 4 to 1 MUX?**

VHDL 4 to 1 Mux (Multiplexer) Multiplexer. Multiplexer (MUX) select one input from the multiple inputs and forwarded to output line through selection line. It consist of 2 power n input and 1 output. The input data lines are controlled by n selection lines.

## How many selection lines are there in a 4 to 1 multiplexer?

Four-to-One Multiplexer In 4:1 MUX, there will be 4 input lines and 1 output line. And to control which input should be selected out of these 4, we need 2 selection lines. Thus, it is evident from the diagram below that D0, D1, D2 and D3 are the input lines and A, B are the two selection lines.

## How to design or construct 4 to 1 multiplexer using logic gates?
