The following BF is to be implemented using 3 external OR gates and a decoder (the decoder block diagram is given below). Input A will be used to enable the decoder and inputs B and C will be connected to A1 and AO, respectively. Let Fi be the output of OR gate 1, F2 be the output of OR gate 2. and F3 be the output of OR gate 3. F1 = A'B + B'C' + BC F2 = B + A'C F3 = AB' + BC Answer the questions below: sample format of answer: (YO,Y1.Y3) //arrange decoder outputs in ascending order and enclose answers in a parentheses 1.
