Question:

A Universal Serial Bus (USB) communication link requires a circuit that produces the sequence 00000001. You are to design a synchronous sequential circuit that starts producing this sequence for input E = 1. Once the sequence starts, it completes. If E = 1, during the last output in the sequence, the sequence repeats. Otherwise, if E = 0, the output remains constant at 1.

(a) Draw the Moore state diagram for the circuit.

(b) Find the state table and make a state assignment.

(c) Design the circuit using D lip- lops and logic gates. A reset should be included to place the circuit in the appropriate initial state at which E is examined to determine if the sequence of constant 1s is to be produced.
