AI Thread Summary
The discussion focuses on determining the main cycle of a counter utilizing JK flip-flops and analyzing the behavior of unused states. The user has identified the necessary inputs for the flip-flops but is unsure how to proceed with the analysis. Key questions include the outcomes when specific combinations of A, B, and C are active or inactive during the next clock cycle. Participants are encouraged to explain the operation of JK flip-flops and the implications of various input states. Understanding these dynamics is crucial for accurately mapping the counter's behavior.

Homework Statement
For the counter shown below, determine the main cycle, and for each of the unused states, show what happens if it starts up there.

Relevant equations
N/AThe attempt at a solution
Based on the diagram in the link I provided, I know that:

JA = QB'
KA = 1
JB = QC'
KB = QC
JC = QA
KC = QA

The problem is I do not know what to do after that. Can anyone explain to me how to do this? Thanks.

Do you know how a JK flip-flop works?

What happens if A,B,C are active and we get the next clock cycle?
What happens if A,B,C' are active?
What happens for all other combinations?
