This book is truly comprehensive and very well made as book. Each device is offered with electronic forms useful for its implementation. We are not starting in calculations of pages for a demonstration, here we go with essential and oriented to practice. It has, for example many chapters for all types patterns transistor in class A, B, AB, etc., with the calculation of component values around. Each concept is discussed with examples and value calculations (high school level to see someone with a 3rd luggage is very well go out). I like this way of presenting the page of a manufacturer's technical documentation to find the component important data, and use this data to do the exercises. Gender simple example, how does one determine a zener diode, with calculating its resistance depending on the voltage range applied to the zener against the current that is requested. Or for example the 3 possible approximations of a diode and their interest as required. Each chapter presents the concepts discussed using keywords, lessons with examples, a reminder of a page on the lessons, exercises (with a question about 2 corrected, but in general the principle is the same as the issue corrected) examples of possible problems finding their practice sample questions that could be asked during interview with a recruiter. Finally it is difficult to sum up a book like this, but it is really too much. It's really not a pompous book, it's super easy to read for self-study and practice to see how a circuit size. There is no resistance values or the output capacitor hat because we know what works as we often encounter ... Each value on the types patterns are justified by calculation. I found a small flat in the book in part Thyristor, triac opto-triac because we were not presented. In particular for switching an alternating voltage from low voltage electronics.
