- Implementation procedure for NAND (NOR) logic:
- Step 1. Express the function in minterm (maxterm) list form.
- Step 2. Write out the minterms (maxterms) in algebraic form.
- Step 3. Simplify the function in SOP (POS) form.
- Step 4. Transform the expression into the NAND (NOR) form.
- Step 5. Draw the NAND (NOR) logic diagram.
