Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a simple circuit using D latches to hold a 4-bit binary number. Describe the behavior when ENABLE is toggled.

💡 Hint: Consider how each latch operates individually within a register context.

Challenge 2 Hard

Explain how D latches can be used in edge cases (like transitions in data signals), and what design considerations should be made.

💡 Hint: Think about synchronization with data signals and the timing of transitions.
