Mux Diagram. If dc 00 then ab selects i1 i2 i3 if dc 01 selects i4 and if dc 10 selects i5. But only one has output line.
One of these 4 inputs will be connected to the output based on the combination of inputs present at these two selection lines. 3 a block diagram of 4 1 mux b logic gate diagram of 4 1 mux. Mux is a device that has 2 n input lines.
Logic diagram for 81 mux you can observe that the input signals are d0 d1 d2 d3 d4 d5 d6 d7 s0 s1 s2 and the output signal is out.
The data inputs of upper 4x1 multiplexer are i 7 to i 4 and the data inputs of lower 4x1 multiplexer are i 3 to i 0. One of these 4 inputs will be connected to the output based on the combination of inputs present at these two selection lines. Show how two 3 to 1 block diagram multiplexers without enable inputs are connected to form a 5 to 1 multiplexer. The symbol used in logic diagrams to identify a multiplexer is as follows.
