Experiment 11 - The 4-to-1 Analog-Multiplexer

The 4-to1 Analog-Multiplexer has four analog inputs (Analog0, Analog1, Analog2 and Analog3). In addition, the multiplexer has the selector inputs (A and B)...

Take a look at the state table...

With the selector input you switch one of the analog inputs to the output (OUT). All you need are a couple of logic gates...
