adder

I wonder if I can get any money for this circuit design.

Hi, I'm working on a project in which I need to create an 8-bit adder with two cascaded 74LS193s, so that when it reaches 255 it starts subtracting, creating some kind of triangular waveform by steps. It works well in the first part of the waveform but in the remaining part it has a sudden jump...

The statement of the problem is to find the YA(D,A,C) and the Y(D,A,C,B) output of the following circuit:

I have been struggling with the following question for a long time. ----------------------------------------------- I am very new to this topic so I'm not sure if any of the following is correct. Here is a simple chart of how I believe the circuit works: State diagram for SUM: State...
