Challenge Problems
Push your limits with challenges.
Question 1
Design a logic circuit with at least five gates. Calculate the total propagation delay given each gate's delay is as follows: AND (3ns), OR (2ns), NOT (1ns).
💡 Hint: Sum the delays of the gates in the series operation.
Question 2
Explain why a carry look-ahead adder significantly improves upon a standard ripple carry adder in terms of speed.
💡 Hint: Consider the order of operations in propagation.
