Answer the questions for parts a and b below. a. What are the required logic operations for a combination of logic gates to be considered a complete logic set for implementing logic functions? Give 3 examples of combinations of logic gates that are complete logicsets. b. Implement the logic function F(a,b,c)=(a+b)c using 2 combinations of logic gates for complete logic sets from your answer in part a. To be clear, the same function F is to be implemented (drawn) twice using different complete logic sets of gates from part a
