Mastering Electronics is a complete, self-contained course for individual study or classroom use, which covers the subject from first principles in an accessible style. The fourth edition has been brought fully up-to-date with current new technology. It has been thoroughly re-organised to fit in with today`s modular teaching, and to make it even easier to follow as a self-study book. The book contains new or completely re-written sections on Computer Simulation of Circuits and Systems, Mobile Telephone Technology, Modern Battery Technology and Computers. Much of the text has been re-written to improve the clarity of the explanations still further. An even wider range of illustrations and an extended glossary of terms are also included.
