Hello, I'm doing some studying for my digital circuits class by looking at previous tests, and I've come across a problem that I cant make sense of.
The problem is such:
Theres a few things I dont understand about this.
The first thing is is the PS/NS table. I understand how the y1+ and y2+ outputs were derived from the D Flip Flops, however, the Z output is described as a function of the inputs (Y1 or NOT Y2) which doesnt make sense to me since the inputs get thrown into the Flip-Flops. Shouldnt Z be a function of Y1+ and Y2+?
Secondly in the state diagram, the only variables that seem to be accounted for are Z and X. I don't understand why the inputs Y1 and Y2 are not represented in the diagram and I can't make sense of it.
I would really appreciate some help on this, as I've had no luck so far figuring it out myself.
