Getting Started

Before we can perform experiments on digital circuits, we must have the means of building those circuits. Of course, we could use one of the circuit simulator programs (eg, SPICE), and they have been improved greatly from their original versions. However, there are random variations between components, even of the same type, that aren't easy to simulate. Therefore, physical experiments with real circuits still provide results that cannot be simulated in every respect.

In addition, simulators cannot provide experience in handling real components, nor demonstrate any physical characteristics or weaknesses of components. To provide that experience, these experiments have been designed to use real-world components.
