a) An overflow occurs when the result of adding two number islarger 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 resultbe interpreted as?
6+6 -7+-3
b) How can someone detect an overflow condition during a 4-bitaddition by examining the sign bits of the two inputs and theresult?
