Counters
1. An asynchronous 4-bit binary counter consists of 4 flip-flops. What is the maximum count value it can reach?
2. A ring counter with 6 flip-flops will have how many distinct states in its counting sequence?
3. A student is designing a modulo-15 up-counter but faces issues. Which of the following could be the problem?
4. In a 2-bit asynchronous counter, if the clock input of the second flip-flop is connected to Q̄ (complement) instead of Q of the first flip-flop, what type of counter is created?
5. For a 3-bit ripple counter using T flip-flops, what should be the T input values for all flip-flops to enable proper counting?
