How would you implement a 4 variable function using 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. The method for the same is described below.
How do you implement an 8 to 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.
How do you implement a function using mux?
Implementation of SOP function using multiplexer
- Step 1: Draw the truth table for the given number of variable function.
- Step 2: Consider one variable as input and remaining variables as select lines.
- Step 3: Form a matrix where input lines of MUX are columns and input variable and its compliment are rows.
What is the number of data input in 4 1 multiplexer?
4 data inputs
We know that 4×1 Multiplexer has 4 data inputs, 2 selection lines and one output.
How many not gates are required for the construction of a 4 to 1 multiplexer?
two NOT gates
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 many and gates are required for a 1 to 8 multiplexer?
For a 1 to 8 multiplexer a total of 8 AND gates are required.
What is variables in truth table?
A truth table has one column for each input variable (for example, P and Q), and one final column showing all of the possible results of the logical operation that the table represents (for example, P XOR Q).
How to implement three variable function using 8 1 multiplexer?
Three variable function can be easily implemented using 8:1 multiplexer. connect 3 input lines to select lines of mux and connect 8 inputs of mux to logic 0 or 1 according to function output. For example, let us say Function is For a 4 variable function, there are 16 possible combinations.
How to design or construct 4 to 1 multiplexer using logic gates?
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, A 0 , A 1 ,… 2 This is how a truth table for 4 to 1 MUX looks like . According to the truth table, the output of the multiplexer… More
How many selection lines required to create a 4 to 1 multiplexer?
It consists input data lines, selection lines and a single output. To construct a 4 to 1 multiplexer, we need to know how many selection lines we required to create a MUX? We require n selection lines, where 2 n represents total input lines and n represents selection lines. (In this case, 2 2 that gives 4 input lines and 2 selection lines).
How many select variables are there for 8 1 MUX?
For 8:1 mux (2^3: 1 where the power represents the number of select variables)there are three select variables (or control variables), so we have to choose any three variables out of four variables of given function.
