4) A digital circuit has 4 binary inputs (A, B, C, D) and binary 2 outputs (F1, F0). The four inputs A, B, C and D represent a BCD code where A is the MSB and D is LSB. If the number of 15 in the inputs is more than the number of Us in the inputs, then F1 = 1, otherwise F1 = 0. If the number of Is in the inputs is less than the number of Os in the inputs, then Pa = 1, otherwise F0 = 0. a) Construct the truth table of the circuit. (10 marks) b) Find the minimum sum of products of the outputs of the circuit. (14 marks)
