a) An overflow occurs when the result of adding two number is larger than can be represented. for example, two 4-bit signednumbers will cause an overflow if their result is greater than +7or less than -8. For example, the following additions will cause anoverflow because their results are outside the range. So, if4-bit addition is performed on these numbers, what will the result be interpreted as?
b) How can someone detect an overflow condition during a 4-bit addition by examining the sign bits of the two inputs and theresult?
