  5. 5. Uses of Multiplexers Used in data communications for several computers to communicate over 1 line Used in radio to select one channel from many Used to route data within a computer Used for function generation
  6. 6. Function Generation using Multiplexers Given the following truth table use an 8/1 Mux to generate F Block Diagram A B C F 0 0 0 0 0 0 1 0 0 1 0 1 0 1 1 0 1 0 0 0 1 0 1 1 1 1 0 1 0 0 0 0 1 1 1 1 A B C S2 S0S1 F
