Edwin C. Craig – författare

The author believes that a good basic understanding of electronics can be achieved by detailed visual analyses of the actual voltage waveforms present in selected circuits. The voltage waveforms included in this text were photographed using a 35-rrun camera in an attempt to make the book more attractive. This book is intended for the use of students with a variety of backgrounds. For this reason considerable material has been placed in the Appendix for those students who find it useful. The Appendix includes many basic electricity and electronic concepts as well as mathematical derivations that are not vital to the understanding of the circuit being discussed in the text at that time. Also some derivations might be so long that, if included in the text, it could affect the concentration of the student on the circuit being studied. The author has tried to make the book comprehensive enough so that a student could use it as a self-study course, providing one has access to adequate laboratory equipment.

The textbook for which this is the laboratory manual takes an unusual approach to teaching the fundamentals of electronics to physicists, namely to show in detail, via photographs from real circuits, the waveforms obtained at various points in an electronic circuit. While these waveforms sometimes look like what is predicted by the simple theories discussed in elementary courses, they are at times quite different. The book uses these differences to develop a more thorough understanding of the individual components and of the circuit as a whole. Most of the mathematical derivations are placed in an appendix, leaving the main text to discuss the physical and visualizable aspects of electronics.
