Multi-Level Logic: Mapping Between Forms

Example: Map AND/OR network to NOR/NOR network

Step 1

Step 2

"Bubbles"

Conserve

"Bubbles"

Verify equivalence

of the two forms

Z = {[(A' + B')' + (C' + D')']'}'

= {(A' + B') • (C' + D')}'

= (A' + B')' + (C' + D')'

= (A • B) + (C • D) ¦

This is the hard conversion!

AND/OR to NAND/NAND more natural

NOR

NOR
