Question [2]: [20 marks] A combinational circuit has 4 inputs (A, B, C, D) and 1 output (F). ABCD represent a majority function. The output of the majority function is equal to 1 if the input variables have more 1's than O's, otherwise the output is 0. a. Construct the truth table of the required circuit. b. Implement the minimized expression of F using 3-level all NAND gate circuit. c. Implement a 2-1 Multiplexer using three-state buffers. d. Give the size of the ROM that stores the values of Y. where Y = 5 x + 5 and X is a 4-bit number
