Multilevel NAND Circuits (4.3)


1. Convert all AND gates to NAND gates with AND-NOT graphic symbols.
2. Convert all OR gates to NAND gates with NOT-OR graphic symbols.
3. Check all the bubbles in the diagram.  For every bubble that is not counteracted by
another bubble along the same line, insert a NOT gate or complement the input literal
from its original appearance.

Example

  • Use NAND gates and NOT gates to implement Z = E’F(AB+C’+D’)+GH






Problem. Implement the circuit with the truth table
