How do you draw a circuit for this method? Thanks
Your task will be to design digital logic circuits that accept input signals {S1, S2, S3, S4} and produce output signals {C1, C2, C3, C4} according to certain design specifications. Method 1 This circuit should produce Ck = Sk (k=1 through 4), with the following exception: As an automobile crosses the boundary between adjacent car wash areas, it is possible that two sensors are simultaneously activated. To prevent any interference...

Construct the 8-bit ripple-carry adder/subtractor for signed integers. Negative numbers are in the 2's complement form. The circuit has inputs X(7:0), Y(7:0), CO, M and outputs S(7:0), carry-out of MSB C8, OFL (OFL 1 when it occurs). The circuit should perform addition and subtraction of 8-bit signed numbers 2. with M-1 and M-0, respectively. a) Obtain the schematic for the 8-bit adder/subtractor with two 4-bit adder/subtractors from problem 1 as building blocks. X, Y, A, B, S can be shown...

Create a full adder and subtractor using ROM (One circuit) I know the minterms adder: S=(1,2,4,7) C=(3,5,6,7) Subtractor: D=(1,2,4,7) B=(1,2,3,7) I just don't know how to use a control variable to draw it as 1 circuit, not 2. I assume it has to have a control variable that is equal to 0 or 1 to choose addition or subtraction, but i don't know how to implement it.
