Solution: next state state 00 0 1 10 0 1 1 0 A 0 0 0 0 1 1 1 1 01 0 11 1 B 0 0 1 1 0 0 1 1 X 0 1 0 1 0 1 0 1 A 0 1 0 0 1 1 1 0 B 0 0 1 0 0 1 1 1 Using K maps obtains DA = A X + B X DB = A X + B X X D Q A C D clock Q B C 8. Derive the state diagram for a circuit that recognizes the occurrence of the of the 4-bit pattern 1001. The circuit has one input X and one output Z . The output is 0 except when the pattern has been recognized, then it is 1 (See example 5-3 in the textbook, the sequence recognizer). Solution: Let A be the initial state of the system 0/0 1/0 0/0 A 1/0 B 0/0 C 1/0 1/1 5 0/0 D...
