None of the above 2.Draw a 2x4 Decoder, and let that EN=1 and inputs "WIW0 =00n; So what is the outputs "y yy 2y ly0 =????" A) 0000 B) 1000 C) 0001 D) 0010 3. Which of the following do you need to construct an 8-bit binary adder? Based on your choice, draw the 8-bit binary adder A. four full adders and four half adders. B. eight half adders C. cight full adders D. two full adders and six half adders 4. Draw the combinatorial Logic circuit that implements the following logic function: F(x,y)=(0,2) Hint: Obtain the logic expression first. 5. Implement the Boolean function F(A,B,C)=(0,2,3,5) using 4 by 1 multiplexer and extemal gates
