Two of the most important applications for the transistor are (1) as an amplifier in analog electronic systems, and (2) as a switch in digital systems. In this experiment we will examine some of the characteristics of transistors in these modes of operation. For this purpose we will investigate one of the common transistors, the bipolar junction

In the off-state the transistor is effectively an open-circuit, and in the on-state it can be modeled by a small resistance, Ron, so we can replace the transistor by the simple switch circuit shown in Figure 4-3b. From this point it is a standard linear circuit problem that we can solve using Laplace techniques.
