7. Which of the following correctly describes output Yi (i: 0 to 7) of the 3-line to 8-line decoder, where mi is the ith minterm of the CBA select lines and E is the enable input?

  1. Yi = mi*E
  2. Yi = (mi*E)'
  3. Yi = (mi*E')'
  4. Yi = (mi'*E)'
  5. Yi = (mi'*E')'




2 is CORRECT. The decoder ith output (i: 0 to 7) is the output of a NAND gate whose inputs are mi and E.
