1. The problem statement, all variables and given/known data The question and provided answer are given: 2. Relevant equations 3. The attempt at a solution I disagree with the answer. Shouldn't there only be three rising edge triggered d flip-flops? I say this because I know if I only had one d flip-flop with the inverter, the clock frequency would be cut in half. Similarly, I would assume that having two d-flip flops with the inverter would cut the clock frequency by 1/4. So would I not need three d flip-flops to cut the frequency by 1/8?
