3. (10+10+10 points) A combinational circuit is specified by the following Boolean functions. Design the combinational circuit using a Multiplexer and external gates, a. F (A, B, C, D) ->m (0, 2, 5, 11, 12, 13, 14, 15). Implement this function witlh 4X1 MUX and external gates if needed. b. F(A, B, C, D)-m (2, 5, 7, 8, 10, 11, 13, 15). Implement this function with 8Xl MUX and external gates if needed. F3(A, B. C, D) =Σm (0, 2,
