This page describes a Qedoc learning module or quiz entitled "Advanced Electronics". You can download the module from this page to put on your computer. You can also launch the module straight off the web using the launch quiz link on the right-hand side of this page. Another way to access this quiz is to install the Qedoc Quiz Player and bring up its directory of downloadable quizzes. Whichever way you choose to use it, it's free.
This is a rebuild of Electronics 1 module, implimenting the use of the Data Tables feature to allow selection of a single question from a group of similar questions. This module covers Test equipment, Semiconductors, Resistors, Capacitors, Inductors, Formulas, Logic, Clippers, Clampers, Oscilators, Counters, and various other Electronic questions.
The module contains the following activities:
- Linear and Analog circuits. • Op-Amp biasing and applications. • Basic Diode applications. • Bipolar transistor circuit biasing for Class A, Class B, and Class C amplifiers. • FET applications. Be able to compare/contrast FET applications with bipolar. • Crystal oscillators and their applications. • Basic power supply design, regulation, and applications. • How to use magnetics for impedance matching. • Basic transformer theory and applications. • Basic tank circuits including RC, RLC, and LC. Be able to calculate RC time constant and resonant frequency. • Q: how it is calculated and how it can be manipulated to change circuit performance. • Similarities and differences between Common-Emitter, Common-Collector, and Common-Base bipolar transistor circuits and how and when to apply each one. • How to calculate voltage and power gain in dB. • How to calculate and improve efficiency of an amplifier. • Basic p-n junctions and how they are used in semiconductor design/applications. • Reactance and phase angle and how to calculate both.
- Digital circuits. • Memory management and bus design. • Small Scale Integration (SSI) digital applications, truth tables, circuit reduction, and Boolean Algebra. • Digital bus applications and bus management/control techniques. • Basic microprocessor applications.
- RF Communications. • Compare and contrast AM, FM, FSK, and PSK transmission methods. Understand LSB, USB,SSB applications and how to decide which to use in various transmission circumstances. • Harmonics: how they are used, and how they are suppressed. • Signal to Noise (S/N) ratio: how it is calculated and how it can be improved. • Basic receiver/transmitter design in the HF, VFH, UHF and L-Band frequency ranges. • Basic antenna applications including resonant frequency, impedance matching, and VSWR. • Coupling and decoupling and how they are used in amplifier/transmitter design. • Distortion: how to calculate it, and how to reduce it. • Efficiency: how to calculate it, and how to improve it.
- General Technician Knowledge. • Electrostatic Discharge (ESD) causes, effects, and mitigation strategies. • Commonly used test equipment including scopes, meters, and curve tracers. • Differences between frequency and wavelength
- All activities. Check your knowledge on all activities.
The following is a short sample of the questions in this module and may help to better assess the level, topic and suitability of the material for your purposes. Images are omitted and the questions may not make complete sense without the context of the interactive answer activities which follow them in the module.

How to use this module
To use a Qedoc learning module, the following procedure is recommended:
- Really easy: click the click here to launch hyperlink at the top right of the page. Then just wait and click your way (if necessary) through any dialogue screens. The module will launch straight off the web.
- Fairly easy: if you wish to have the module downloaded to your desktop, then start the Qedoc Quiz Player (which you can download and install on your computer if you haven't done so yet) and run through the starting dialogues until it presents you with a list of modules to load. Switch to the online learning modules tab, and the Qedoc Quiz Player will download a list of currently published modules from the web. Choose your desired module (this one) from the list. A local copy will then be kept on your computer for future use.
- Not so easy: click the download link at the bottom of the "quick facts" box and the module's ZIP file will download to your desktop. To actually use this, however, you must move it to the /player/modplay subdirectory of whichever directory the Qedoc software is installed in (usually /programme files/qedoc).
