Question 1: Given: A 100101102, B=11110102, answer the following questions? A) If A and B are unsigned numbers, what is A x B in binary? Show the partial products. B) If A and B are 2 complement numbers, what is A + B? Show your work. C) If A and B are signed numbers, what is A - B using 2' complement subtraction? Show your work. Question 2 Use only 8:1 Multiplexer to implement the following function: G = (A+B+C)(A+ C + D)(B+C + D)(B+C+D) Do not use any additional logic gates. Question 3: (1) use K-Map to determine the minimum-cost SOP and POS expressions for the function: f(x1, x2, x3) = m(4,6,8,10,11,12,15) + D (3,5,7,9) Question 4: Derive a minimum-cost realization of the four-variable function that is equal to 1 if exactly two or exactly three of its variables are equal to 1; otherwise, it is equal to 0.
