A combinational circuit is specified by the following three Boolean functions:
F₁(A, B, C)= ∑(1,4,6)
F2(A, B, C)= ∑(3, 5)
F3(A, B, C)= ∑(2, 4, 6, 7)
Implement the circuit with a decoder constructed with NAND gates and NAND gates connected to the decoder outputs. Use a block diagram for the decoder.
