Lessons in Electronics - Experiments

2007-08-23T07:42:00.001-07:00

Write new experiments for any and all chapters.

This is perhaps the easiest way for someone to contribute to the book: write a short electric/electronic circuit experiment, complete with parts list, diagrams and illustrations, and instructions. A lot less work than writing a whole chapter or chapter section!

Lessons in Electronics - References

2007-08-23T07:31:00.000-07:00

Write a chapter on basic algebra techniques, especially equation-solving and "story problem" solving.
Write a chapter on oscilloscope usage.

Lessons in Electronics - Digital Circuits

2007-08-23T07:29:00.000-07:00

Complete chapter 7: "Boolean Algebra."
Write "Combinational Logic Functions" chapter (#9).
Complete chapter 11: "Counters."
Write "Shift Registers" chapter (#12).
Expand coverage of microprocessor architecture and function in chapter 16.
Expand coverage of digital memory to include more modern technology in chapter 15, especially optical and magnetic media.

Lesson in Electrionics - Semiconductors

2007-08-23T07:26:00.000-07:00

Complete chapter 6: "Insulated-Gate Field-Effect Transistors."
Complete chapter 3: "Diodes and Rectifiers."
Complete "Practical Analog Semiconductor Circuits" chapter. See section headings within this chapter for an idea of the content I'm planning on. The completion of the first section ("Power supply circuits") should be top priority in this chapter.
Write "Active Filters" chapter (#10).
Write "DC Motor Drives" chapter (#11).
Write "Inverters and AC Motor Drives" chapter (#12).
Complete chapter 2: "Solid-State Device Theory." What I'm looking for is a chapter that explains the quantum mechanisms of semiconductor devices in as much detail possible without involving calculus. Impossible? Perhaps, but it's worth a try! I cringe every time I read an introductory text on semiconductors that attempts to describe electron and hole interaction in terms of classical physics . . .
Complete chapter 4: "Bipolar Junction Transistors."
Complete chapter 5: "Junction Field-Effect Transistors."
Complete chapter 7: "Thyristors." Discuss 4-quadrant firing of TRIACs.
Complete chapter 8: "Operational Amplifiers." Add section on chopper-stabilization of amplifiers.

Add "Scott-T" transformer discussion to Transformers chapter (#9).
Add a section or two discussing "Smith charts" to chapter 14: "Transmission Lines"
Discuss balanced versus unbalanced transmission lines in chapter 14, and the operation of "balun" transformers.
Re-take screenshots of Winscope in time-domain and frequency-domain modes. Designate the new screenshot files 22*.png, according to the naming convention for screenshot image files.
