Experiment 5 - The NAND-Transistor Logic (RTL)

In the NAND logic the result of the AND logic is negated. Again, you can build it with a transistor circuit.

The truth table shows you the NAND logic...

A B Q 0 0 1 0 1 1 1 0 1 1 1 0 Truth table of the NAND logic.

Surely you recognize the similarities with the NOT-transistor logic...

In the next experiment you are applying this to the NOR-transistor logic.
