What is a 4-to-1 multiplexer?
A 4-to-1 multiplexer consists four data input lines as D0 to D3, two select lines as S0 and S1 and a single output line Y. That means when S0=0 and S1 =0, the output at Y is D0, similarly Y is D1 if the select inputs S0=0 and S1= 1 and so on.
Where is multiplexer in Multisim?
For making 4:1 MUX/ MULTIPLEXER, we need the following components:- 1) 4 – INPUTS(D0,D1,D2,D3). 2) 2 – SELECT LINE(S0,S1). 3) 2 – NOT GATE. 4) 4 – AND GATE.
What are the inputs of 4 * 1 mux?
In the 4×1 multiplexer, there is a total of four inputs, i.e., A0, A1, A2, and A3, 2 selection lines, i.e., S0 and S1 and single output, i.e., Y. On the basis of the combination of inputs that are present at the selection lines S0 and S1, one of these 4 inputs are connected to the output.
What is a multiplexer with logic circuit and function explain the working of 4 to 1 line multiplexer?
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. data control 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.
How do you make a mux?
To construct a 4:1 MUX using a 2:1 MUX, we will have to combine three 2:1 MUX together. The end result should give us 4 Input pins, 2 Control/Select Pins and one output pin. To achieve the first two MUX is connected in parallel and then the output of those two are feeded as input to the 3rd MUX as shown below.
How may inverters are needed to implement 4 1 multiplexer?
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….Detailed Solution.
| Given Multiplexer | To be implemented | Required |
|---|---|---|
| 8 x 1 | 64 x 1 | 8 + 1 = 9 |
What is multiplexer draw the circuit diagram of 4/1 multiplexer explain its working in brief?
The block diagram of 4×1 Multiplexer is shown in the following figure. 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….4×1 Multiplexer.
| Selection Lines | Output | |
|---|---|---|
| 1 | 0 | I2 |
| 1 | 1 | I3 |
How many 1 to 4 Line demux are required to construct a 1 to 64 line Demux?
Therefore, for 1:4 demultiplexer, 2 select lines are required. Explanation: A demultiplexer sends a single input to multiple outputs, depending on the select lines.
What is a multiplexer with a 4 bit data select input?
A multiplexer with a 4 – bit data select input is a. 16 : 1 multiplexer.
