Why are demux not universal combinational circuit?
The internal of a demux is: It contains a NOT and an AND. Then, why is it not universal? Using demorgans law can't we get OR?

Number of Input and Output lines
A input function can take values {0,1,2,4,6,7} and the output can take {0,2,4,6}. Then how many bits (lines) are required for input and output ? My doubt is: Since only 4 different states are required to be represented (for output) , so why not use only 2 bits?

Complement vs. dual?
Is COMPLEMENT OF DUAL=DUAL OF COMPLEMENT? How can we relate in terms of minterms, like if f(x,y,z)=0,1,2,3, then complement = 4,5,6,7 what would be the dual?
