Multi-Level Logic: Conversion of Forms

NAND-NAND and NOR-NOR Networks

DeMorgan's Law: (A + B)' = A' • B'; (A • B)' = A' + B'

Written differently: A + B = (A' • B')'; (A • B) = (A' + B')'

In other words,

OR is the same as NAND with complemented inputs

AND is the same as NOR with complemented inputs

NAND is the same as OR with complemented inputs

NOR is the same as AND with complemented inputs

OR/NAND
