Challenge Problems
Push your limits with advanced challenges
A ripple counter with 5 flip-flops is used in a speed measurement device. Calculate its modulus and the maximum clock frequency if each flip-flop has a propagation delay of 30 ns.
💡 Hint: First, calculate modulus, then total delay for frequency.
Design an asynchronous counter with a modulus of 15 using flip-flops. How many flip-flops do you need, and what modifications would you make?
💡 Hint: Look for the closest power of two that meets the requirement.
