How many flip-flops are required to produce a divide-by-10 device?a.4b.8c.3d.2
Question
How many flip-flops are required to produce a divide-by-10 device?a.4b.8c.3d.2
Solution
The answer is c.3. To create a divide-by-10 device, you would need a 3 flip-flop counter. This is because 2^3 = 8, which is the nearest power of 2 that is greater than 10. So, three flip-flops can count from 0 to 7 (8 states), but we can reset the counter after the 10th state to make it a divide-by-10 device.
