4. Given values of a, b, and c as shown, write the result of expressions shown below. BENC 241 SEMESTER 1 (2018/2019 Assume: is (3:0), bis [3:0), c is [5:0] Assume: a = 4'60010, b = 4'61010, c = 6'6001101 Evaluate the following expressions: a & b = ? a & & b = ? + b ? a 11 b = ? a | b = ? a = C, a = ? c = b, c = ? I a = ? a - b = ? & b = ? 5. What is one advantage and one disadvantage that designs using FPGAs have compared to designs using standard cells
