A universal logic gate is one which can be used to generate any logic function. Which of the following is a universal logic gate?

How many two-input AND and OR gates are required to realize Y = CD+EF+G?

How many two input AND gates and two input OR gates are required to realize Y = BD + CE + AB?

The following switching functions are to be implemented using a decoder:
f1 = ∑m(1, 2, 4, 8, 10, 14) f2 = ∑m(2, 5, 9, 11) f3 = ∑m(2, 4, 5, 6, 7)
The minimum configuration of decoder will be
