How do you implement a function using 8 1 multiplexer?
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. The method for the same is described below.
What function is implemented with multiplexer?
A multiplexer performs the function of selecting the input on any one of ‘n’ input lines and feeding this input to one output line. Multiplexers are used as one method of reducing the number of integrated circuit packages required by a particular circuit design.
What you mean by multiplexer explain using implementation of logic function?
It is a combinational circuit which have many data inputs and single output depending on control or select inputs. Multiplexer can act as universal combinational circuit. All the standard logic gates can be implemented with multiplexers.
Which of the following functions are performed by the digital multiplexer?
A multiplexer performs the function of selecting the input on any one of ‘n’ input lines and feeding this input to one output line. Multiplexers are used as one method of reducing the number of integrated circuit packages required by a particular circuit design. This in turn reduces the cost of the system.
What is 8×1 multiplexer?
An 8-to-1 multiplexer consists of eight data inputs D0 through D7, three input select lines S0 through S2 and a single output line Y. Depending on the select lines combinations, multiplexer selects the inputs.
Is used to implement the Boolean functions?
Explanation: To implement a Boolean function logic gates are used. Basic logic gates are AND, OR and NOT.
What is the input for an 8 to 1 multiplexer circuit?
What is a 3 to 8 decoder?
A 3 to 8 decoder has three inputs (A,B,C) and eight outputs (DO to D7). Based on the 3 inputs one of the eight outputs is selected. The truth table for 3 to 8 decoder is shown in table (1).
What is multiplexer implement 8 is to 1 multiplexer using basic gates?
How is the Boolean function implemented in multiplexer?
The inputs, corresponding to the minterms (0, 1, 3, 5, 7) are connected to the logic 1 and remaining terms to the logic 0 (grounded). If the boolean expression has n+1 variables, we take only n variables as the selection line of the multiplexer.
Can a 8 : 1 multiplexer be used for a 4 input function?
It’s possible to use an 8:1 multiplexer to implement any 3-input logical function, but can we use it to implement a 4-input function? On the one hand, some logic problems never seem to go away. On the other hand, these problems can “keep on giving” when it comes to their ability to teach us things.
What are the selection lines in 4 : 1 multiplexer?
For 4 : 1 multiplexer, there should be 2 selection lines. So from the given 3 variables, the 2 least significant variables (B, C) are used as selection line inputs. Let us derive the four inputs of 4 : 1 multiplexer using the implementation table.
How are multiplexers used in a digital circuit?
Digital Circuits – Multiplexers. Multiplexer is a combinational circuit that has maximum of 2 n data inputs, ‘n’ selection lines and single output line. One of these data inputs will be connected to the output based on the values of selection lines. Since there are ‘n’ selection lines, there will be 2 n possible combinations of zeros and ones.
