The clearly structured layout of the book, with numerous tasks, in-depth exercises, and corresponding detailed solution descriptions, facilitates the generalization of circuit principles and the development of one's own circuits. It is therefore particularly well-suited for self-study and as a teaching aid. The content is exemplary and generalizable. The book's current technical relevance is demonstrated through an appropriate description of circuit simulation using the user-friendly software LTspiceIV / SWCADIII. This free software is professional and adheres to PSPICE computational algorithms. Circuit examples are described in terms of their functionality, and the results are visualized through measurement or simulation techniques. This edition has been expanded to include an open-ended project on a pulse-width modulated Li-Ion battery charging regulator.
