🔍 Key Concepts

• Flip-flop frequency division (each flip-flop in toggle mode divides frequency by 2) • Binary counting sequence and how many states each flip-flop provides • Relationship between required division ratio and number of flip-flops: (2^n)

💭 Think About

• If one flip-flop divides the input frequency by 2, what happens when you connect another flip-flop to the output of the first? • What power of 2 gives you a division by 4, and how many flip-flops are needed to achieve that? • Think of how many flip-flops are needed in a binary counter to count 0–3; how is that related to dividing by 4?

✅ Before You Answer

• Confirm that each flip-flop in toggle mode divides frequency by 2. • Calculate which power of 2 equals 4 (i.e., (2^n = 4)). • Match the exponent n from that equation with the number of flip-flops required.
