What is multiplexer in Boolean algebra?
The multiplexer, shortened to “MUX” or “MPX”, is a combinational logic circuit designed to switch one of several input lines through to a single common output line by the application of a control signal. The most basic type of multiplexer device is that of a one-way rotary switch as shown.
What is the output function of the multiplexer?
Such a circuit is referred to as a 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.
How to implement Boolean function in multiplexer electrically?
Type #1 1 The first step is to select the multiplexer. If the given expression has n variables, then determine the multiplexer… 2 Connect the inputs, that correspond to the given minterms to logic 1. 3 Connect all the other inputs to the ground (logic 0). 4 Connect the input variables (P, Q, R) as the selection lines.

How many variables are in a Boolean function?
In the given boolean expression, there are 3 variables. We should use 2 3 : 1 = 8 : 1 multiplexer. But as per the question, it is to be implemented with 4 : 1 mux. 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.
Which is the correct definition of a multiplexer?
The multiplexer, shortened to “MUX” or “MPX”, is a combinational logic circuit designed to switch one of several input lines through to a single common output line by the application of a control signal.
Which is input does a multiplexer circuit control?
The input A of this simple 2-1 line multiplexer circuit constructed from standard NAND gates acts to control which input ( I 0 or I 1 ) gets passed to the output at Q.
