2 To 1 Mux Boolean Equation. Give the values of. In this way any boolean expression having n variables can be implemented with 2 n 1 to 1 multiplexer.
We can confirm this in the following boolean expression. Since there are two input signals only two ways are possible to connect the inputs to the outputs so one select is needed to do these operations. F a b c ab ac where a not a.
The top line on the box labelled mux is the data select line and selects one of two hence 2x1 inputs to appear at the output.
A multiplexer of 2 n inputs has n selected lines are used to select which input line to send to the output. We can confirm this in the following boolean expression. Bout f a b c m 1 2 3 7 from these boolean functions a demultiplexer for producing full subtractor output can be built by properly configuring the 1 to 8 demux such that with input d 1 it gives the minterms at the output. As we only have one control line a then we can only switch 2 1 inputs and in this simple example the 2 input multiplexer connects one of two 1 bit sources to a common output producing a 2 to 1 line multiplexer.
