The following topics are covered in the video:
0:00 What is Multiplexer?
3:10 The logic circuit of 2 to 1 multiplexer and 4 to 1 Multiplexer
6:12 8 to 1 Multiplexer using 4 to 1 Multiplexer (and 2 to 1 MUX)
8:51 8 to 1 Multiplexer using 2 to 1 Multiplexers
11:58 16 to 1 Multiplexer using 4 to 1 Multiplexers

What is Multiplexer?
The Multiplexer is the combinational circuit that has M inputs, 1 output, and N selection lines. And using the selection lines, any one of the inputs is connected to the output. The multiplexer is often referred as MUX during the block diagram representation.
If the multiplexer has M inputs then the total number of selection lines are log 2 (M).
Or if the multiplexer has N selection lines then the total number of inputs are 2 ^N.
Depending on the number of inputs and selection lines, there are different types of multiplexers, e.g 2 x 1 MUX, 4 x 1 MUX, 16 x 1 MUX, etc.
Large Multiplexer using Small Multiplexer:
As the number of inputs to the multiplexer increase, the required number of AND/ OR gates also increases. And hence the cost and the complexity of the design also increase. So, typically the large multiplexer is designed using the small multiplexers.
In this video, the design of 8 x 1 MUX using 4 x 1 MUX and 2 x 1 MUX is explained.
Boolean Function Implementation using Multiplexer:
The multiplexer can be used to implement different Boolean Functions.
In this video, two different methods for Boolean Function Implementation are shown using examples.
This video will be helpful to all the students of science and engineering in understanding what is multiplexer and how to implement Boolean functions using the Multiplexer.

how do you do the last example, if the selectors are BCD, cause it would be different right?

@ALLABOUTELECTRONICS Жыл бұрын

Yes, it is different. Of course, you can make a table and find the relevant inputs. But it won't be convenient. Because, now your minterms in the table are not in a sequence. For example, for BCD = 0, you are grouping minterm m0 and m8. Likewise, for BCD = 001, in the table, two minterms will be m1 and m9. So, of course, you can make such groups, and find the value of each pin in terms of variable A. But it won't be a straight forward. I hope, it will clear your doubt.

are data lines and selection lines the same thing?

@ALLABOUTELECTRONICS Жыл бұрын

Data lines are the input lines, where we apply the input. Selection lines, select the specific input. And that input appears at the output. For example, in 4 *1 MUX, if selection inputs are 00, then first input will appear at the output. I hope, it will clear your doubt.

is it compulsary to starting numbering the selection lines S0, S1, S2.. from right to left ?

@ALLABOUTELECTRONICS 6 ай бұрын

No it is not compulsory. But when you have multiple lines, and when you write the truth table for the selection inputs then S2 represents the MSB, an S0 represents the LSB. So, naturally when we label these lines in the multiplexer diagram, then we used to represent them in the same order.

1.If possible explain how the output F came in last two tables.

@ALLABOUTELECTRONICS 10 ай бұрын

I think, you are talking about the implementation of Boolean function using the multiplexer. In that, we have assumed that we have some function F, which is 1 for the specific input combination. And the corresponding truth table is represented. Here function arbitrarily chose.

@isharajput9991 11 ай бұрын

Sir how can we find the value of F in table

@ALLABOUTELECTRONICS 11 ай бұрын

Typically, while solving such questions, the Boolean expression of the function F will be given. And from the Boolean expression, you will get to know that, for what minterms, the function F is equal to 1.
