4.5. Demultiplexers (DEMUX)

Try these first

1. 1.

   What does a demultiplexer do?

   Hint

   Think about how it directs signals.

2. 2.

   If a DEMUX has 8 outputs, how many control lines does it need?

   Hint

   Use the formula C = log2(N).

3. 3.

   What does a DEMUX do?

   • Combines multiple signals
   • Routes one signal to multiple outputs
   • Stores data
   • None of the above

   Hint

   Recall the basic function of a DEMUX.

4. 4.

   True or False: A DEMUX utilizes control signals to determine which output line receives the input signal.

   • True
   • False

   Hint

   Think about how choices are made in the circuit.

5. 5.

   Design a DEMUX circuit for 8 outputs using basic logic gates. Explain your design choices.

   Hint

   Consider how logic gate arrangements can ensure only one output is active at a time.

6. 6.

   Explain how a DEMUX can facilitate communication between multiple devices in a network.

   Hint

   Think about how devices receive specific data without interference.
