Question

classmates designed a state machine for the state diagram below. Unfortunately, h dn t supply the design details (ie, the state table), only the combinational logic expressions:- 2. One of your While it's clear that the design was for 3 JK flip flops and a single input X, and the ordering of Q2, Qi, and Qo is obvious from the diagram, your TA wants to know what happens if the circuit somehow starts in one of the unused states. Figure this out and add the results to the state diagram. Be sure to indicate how the value of the input Xmpacts your answers 02 01 00 001 100 010

Explanation / Answer

In this design zero state has no meaning, if system goes to zero then it has to reset to one of other states from 1 to 7. Q2Q1Q0 are present states Q2+,Q1+, Q0+ are next states

Q2 Q1 Q0 Input(X) Q2+ Q1+ Q0+ 0 0 1 0 0 0 1 0 0 1 1 0 1 0 0 1 0 0 0 1 0 0 1 0 1 1 0 0 0 1 1 0 0 1 1 0 1 1 1 0 1 0 1 0 0 0 1 0 0 1 0 0 1 0 0 1 1 0 1 0 1 0 1 1 0 1 1 0 1 1 1 1 0 0 1 1 0 1 1 0 1 1 0 1 1 1 1 0 1 1 1 1 1 1 1 0 1 1
