I am having a tough time understanding sequential logical circuits, and example is here, maybe "flip flops" rings a bell. I just can't understand on my own what's going on with the truth table for it, how are things going in? like it says R=1 and S=0, so what goes on and where does the 2nd input for each NAND gate come from? generally, I don't understand, but the stuff before I do.
look at the 2nd diagram on the above page, that's what I mean,
