Q10. A combinational circuit is specified by the following three Boolean functions below. Implement the circuit with a decoder constructed with NAND gates and NAND or AND gates connected to the decoder outputs. Use a block diagram for the decoder. Minimize the number of inputs in the external gates: F1(A, B, C) = {(1,4,6) F2(A, B, C) = E(3,5) F3(A, B, C) = {(2, 4, 6, 7) ==
