What is the Boolean function for multiplexer?
multiplexer is used to implement the above function. We connect boolean logic ‘1’ at the inputs corresponding to control inputs ABC= 1, 2, 4, and 6. For all other input boolean logic ‘0’ is connected. as control input and then determine what should be connected at the inputs of multiplexer as shown below.
How do you implement a function into a multiplexer?
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 function of multiplexer?
The basic function of a multiplexer: combining multiple inputs into a single data stream. On the receiving side, a demultiplexer splits the single data stream into the original multiple signals.
How do you solve a multiplexer?
Solving multiplexer circuit
- Firstly truth table is constructed for the given multiplexer.
- Select lines in multiplexer are considered as input for the truth table.
- Output in truth table can be four forms i.e. ( 0, 1, Q, Q’).
- Now with the help of truth table we find the extended expression.
What is multiplexer function?
What is the use of a multiplexer?
A multiplexer makes it possible for several input signals to share one device or resource, for example, one analog-to-digital converter or one communications transmission medium, instead of having one device per input signal. Multiplexers can also be used to implement Boolean functions of multiple variables.
What is multiplexer in DLD?
Multiplexer is a combinational circuit that has maximum of 2n 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. So, each combination will select only one data input. Multiplexer is also called as Mux.
What is the Boolean expression for 4 to 1 multiplexer?
The Boolean expression for this 4-to-1 Multiplexer above with inputs A to D and data select lines a, b is given as: Q = ab A + a b B + a bC + abD. In this example at any one instant in time only ONE of the four analogue switches is closed, connecting only one of the input lines A to D to the single output at Q.
How does the input a of a multiplexer work?
The input A of this simple 2-1 line multiplexer circuit acts to control which input ( I 0 or I 1 ) gets passed to the output at Q. From the truth table we can see that when data select input, A is LOW (logic 0), input I 1 passes its data to the output while input I 0 is blocked.
How is the demultiplexer different from the multiplexe R?
The Demultiplexer or “Demux” for short, is the exact opposite of the Multiplexe r. The demultiplexer takes one single input data line and then switches it to any one of a number of individual output lines one at a time. The demultiplexer converts a serial data signal at the input to a parallel data at its output lines as shown below.
What is the binary address for multiplexer in Q?
So for this example to select input B to the output at Q, the binary input address would need to be “a” = logic “1” and “b” = logic “0”. Thus we can show the selection of the data through the multiplexer as a function of the data select bits as shown.
