State Diagrams
1. A given state diagram has 8 distinct states. The number of flip-flops required to make the circuit are:
2. A circuit has three inputs A, B, C and one output Y. The output Y is 1 when the binary value of the inputs represents an odd number, and 0 otherwise. What is the expression for Y?
3. For making a mod-6 counter, Mankar used 3 flip-flops without any additional gates. How many states will be skipped?
4. How many columns are required in a state table for a circuit with 1 D flip-flop, 2 inputs, and 1 output?
5. How many rows are required in a state table for a circuit with 2 D flip-flops, 2 inputs, and 2 outputs?
