Experiment 9 - The 2-to-1 Analog-Multiplexer

The 2-to1 Analog-Multiplexer has again two inputs (Analog0 and Analog1). However, this time they are analog inputs. In addition, the multiplexer has the selector input (A)...

Take a look at the state table...

With the selector input you switch one of the inputs to the output (OUT). All you need are a couple of NOT gates...
