When subtracting binary numbers, the 2’s complement of B is added to A, and because 10 10 = 1010 2 and 7 10 = 0111 2, 10 – 7 = 3 gives 1010 + 1001 = 10011, which exceeds the word size of the output and causes unsigned overflow. At the same time in the signed integer timing diagram, A = … ................
