Consider three 4-variable functions f1, f2 and f3, which are expressed in sum-of-minterms as
f1 = Σ(0, 2, 5, 8, 14),
f2 = Σ(2, 3, 6, 8, 14, 15),
f3 = Σ(2, 7, 11, 14)
For the following circuit with one AND gate and one XOR gate, the output function f can be expressed as :
f1 = Σ(0, 2, 5, 8, 14),
f2 = Σ(2, 3, 6, 8, 14, 15),
f3 = Σ(2, 7, 11, 14)
For the following circuit with one AND gate and one XOR gate, the output function f can be expressed as :
