How do you make an 8 to 1 multiplexer?
To implement the 8×1 multiplexer, we need two 4×1 multiplexers and one 2×1 multiplexer. The 4×1 multiplexer has 2 selection lines, 4 inputs, and 1 output. The 2×1 multiplexer has only 1 selection line. For getting 8 data inputs, we need two 4×1 multiplexers.
How many not gates are required for the construction of a 8 * 1 multiplexer?
3 NOT gate
8 to 1 Multiplexer Circuit Diagram To implement an 8-to-1 multiplexer circuit we need 8 AND gates, an OR gate, and a 3 NOT gate. In 8-to-1 multiplexer, eight inputs D0, D1, D2, D3, D4, D5, D6, and D7, three data select lines that are S0, S1, and S2 as 8-inputs represent 2m = 23 data select lines.
What is the logic function for a 8 1 mux?
The given function is in terms of minterms and is to be implemented using a 8:1 MUX. An 8:1 MUX has three select lines, whereas the given function is a 4 variable function. Hence a logic is needed to give combination of A as inputs while only B, C and D as select line inputs.
What is electronic mux?
A multiplexer (MUX) is a device that can receive multiple input signals and synthesize a single output signal in a recoverable manner for each input signal. It is also an integrated system that usually contains a certain number of data inputs and a single output.
How do you make a truth table for a multiplexer?
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 | 1 | I3 |
How many selected lines would be required for an 8 line to 1 line multiplexer?
3
An 8 × 1 multiplexer selects one of the 8 inputs and presents it to the output, i.e. So the number of select lines will be 3.
What is difference between Mux and Demux?
Demultiplexer is a data distributor which takes a single input and gives several outputs.In demultiplexer we have 1 input and 2n output lines where n is the selection line….Difference between of Multiplexer and Demultiplexer :
| Multiplexer | Demultiplexer |
|---|---|
| It is known as Data Selector | It is known as Data Distributor |
What are multiplexers and demultiplexers?
Multiplexer refers to a type of combinational circuit that accepts multiple inputs of data but provides only a single output. The demultiplexer refers to the type of combinational circuit that accepts just a single input but directs it through multiple outputs.
What is MUX in CPU?
A multiplexer (MUX) is a device that can receive multiple input signals and synthesize a single output signal in a recoverable manner for each input signal.
