For a hands-on, two-semester electronics lab course. The emphasis is first on understanding the characteristics of basic circuits including resistors, capacitors, diodes, and bipolar and field effect transistors. The students then use this understanding to construct more complex circuits such as power supplies, differential amplifiers, tuned circuit amplifiers, a transistor curve tracer, and a digital voltmeter. In addition, students are exposed to special topics of current interest, such as the propagation and detection of signals through fiber optics, the use of Van der Pauw patterns for precise linewidth measurements, and high gain amplifiers based on active loads.
