Experiment 7 - The NOR gate

Truth Table of the NOR logic.

NOR symbol in circuit diagrams.

A NOR circuit. (Enlarge)

With the circuit shown and the C-MOS 4001 you can build the NOR circuit.

However, you can also leave this circuit out. The principle of the circuits is surely clear to you.

All that remains is the "negation" of the XOR gate...
