Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a 4:16 demultiplexer using combinational logic. Provide a truth table and possible applications.

💡 Hint: Remember how the select lines determine which output is activated.

Challenge 2 Hard

Create a scenario in which using an ALU leads to ambiguous results, justifying the need for control signals.

💡 Hint: Focus on how precise commands can dictate operations.
