Consider the following multiplexer where 0, 1, 2, 3 are four data input lines selected by two address line combination of CB = 00, 01, 10, 11 respectively and f is the output of the multiplexer
The function f(S2, S1, A) implemented by the above circuit is?
1
S2 ⊙ S1 ⊙ A
2
S2 ⊙ S1 ⊕ A
3
S2 ⊕ S1 ⊙ A
4
S2 ⊕ S1 ⊕ A
