Final answer:
Unable to provide a logic diagram, state table, or state equations for the sequential circuit due to missing specific information. The question seems to confuse concepts from Kirchhoff's rules in circuit analysis with the design of sequential digital circuits.
Step-by-step explanation:
The question involves designing a sequential circuit using two JK flip-flops, with given input equations and the requirement to determine the logic diagram, the state table, and derive the state equations for the flip-flops A and B. Unfortunately, without the specified figure and flip-flop input equations provided in the question, it is impossible to draw the logic diagram or tabulate the state table, or derive the state equations for flip-flops A and B.
To correctly tackle a question like this, one would typically use the JK flip-flop triggering equations, logic gate symbols, and truth tables to construct the requested circuit elements. However, due to the lack of specific information needed to create these details, the answer cannot be provided. Since the question references Kirchhoff's rules and junctions, it seems there may be a misunderstanding or typo, as these are concepts in circuit analysis, not directly related to sequential digital circuits.
