Boolean Function Implementation using block diagram method (NOR Implementation)

IntroductionThe NOR function is the dual of the NAND function. For this reason, all procedures and rules for NOR logic are the dual of the corresponding procedures and rules developed for NAND logic.

The implementation of a Boolean function with NOR gates requires that the function be simplified in Product Of Sum (POS) form.
