I have been given a Sequential Circuit with two d flip flops, two inputs and one output.

I wanna ask if a step-by-step solution to the "State table" can be made because I cannot simply understand how to do it.

I try with the formula where I said:

Q_1 = D_1 = X Y + X B Q_2 = D_2 = X A + X B Z = A

I also try to make it in a simulator, where I got confused and ended up making a table that didn't includes "01" as an outcome But I always ended up making a mistake that ruined my outcome.

Long story short, can the Master Expert explain it so thoroughly that even a 5-year-old also will understand it.

Best Regard Daniel.B
