"In this exercise you have to make a combinatorial digital circuit. The circuit has a bit width of 2 bit. The circuit also has two control signals A and B which decide the function of the circuit according to TABLE 1(attachement). The signals in and out are on 2's complement form."
I am completely lost on where to start here. First of all the table makes no sense to me, what does "Out = In" actually mean, and "Out = In-1" etc. perhaps that can give me some kind of clue on where to start. I read up on the basics of logic circuits and know what an AND, OR, NOT, NAND, NOR and XOR gate is, but I am not sure how all that helps me solve this exercise.
Thank you all!
