Let's go...

The first logical circuits were constructed with resistors and transistors and were refered to as resistor-transistor logic (RTL). These circuits, however, had some disadvantages and to compensate, diodes were added. These new circuits became known as diode-transistor logic (DTL).

Increasingly logic circuits were incorporated into integrated circuits. Since producing a transistor in an integrated circuit is as consuming as producing a diode, the transistor-transistor logic (TTL) was developed. Even today, TTL form the basis for an entire class of integrated circuits.

In this first part you get to know the transistor logic in 15 Experiments. Here you build the circuits of the RTL, DTL as well as TTL.

The second part (Go on...) describes in another five experiments applications of the transistor logic.

Let's go...and have fun...
