4.4. Multiplexers (MUX)

Try these first

1. 1.

   What is the primary purpose of a multiplexer?

   Hint

   Think about what a MUX does in a circuit.

2. 2.

   How many inputs can a 2:1 MUX handle?

   Hint

   Look at the numbers in the name 2:1.

3. 3.

   What does a multiplexer do?

   • Combines signals
   • Selects one input
   • Filters signals

   Hint

   Remember the purpose of a MUX in data management.

4. 4.

   True or False: A 4:1 multiplexer has 4 inputs and can output 2 signals simultaneously.

   • True
   • False

   Hint

   Consider the definition of a multiplexer.

5. 5.

   Design a 8:1 multiplexer circuit using basic logic gates and explain the advantages of using a MUX in digital design.

   Hint

   Consider how inputs are combined through the gates and how the control signals are used to select.

6. 6.

   Develop a truth table for a 4:1 multiplexer showing all possible combinations for the inputs and control lines.

   Hint

   Remember that the control lines dictate which input gets passed through to the output.
