This question is from the subject Digital Logic Design. Assume your register number SF20-BEC-xxx (excluding the dashes -) is in Hexadecimal, where xxx are the three digits of your registration number. a) Represent your registration number in the binary.b) Split the ten digits of your registration into two Hexadecimal numbers M and N, where the left most five digits make number M and the right most five digits make number N. Using r’s complement, subtract N from M. In other words, calculate M – N. Solve the question for registration no SF20-BEC-156.
