Consider the following 4-bit Carry-Ripple Subtractor (NOT an Adder). Note that each Full Subtractor (FS) stage has a wi (borrow-in) input and a wo (borrow-out) output. a3 b3 a2 b2 al bi a bo wi || a b wi a bwi a b wi a b wi FS3 FS2 FS1 FSO wo S wo wo wo s W, D W, D WD. W. D A. Suppose this system is loaded with two signed binary inputs A = 0010 and B = 0111. Compute and record the outputs of each stage as well as Win for the first stage using the following table. W3 D3 W2 D2 W1 D1 Wo Do Win = B. Since the wo bit of the final stage of this 4-bit Subtractor always represents -16, show that your results of part A are consistent with the equivalent decimal value of this system's output.
