Finally, the book I was looking for !! I debuted in electronics and I just regret having learned formulas stupidly while with this book everything is fun, it is tested and after you learn! the layout is nice and colorful schematics are clear by following the evolution of the phenomena seems clear and fast moving! over the end a glossary specifically grouping the components required for each experiment (a headache or else ...) I tested other books of its kind, a yellow and black of a certain well-known collection, very good too but this aspect has not "hand in dirty" indispensable (currently I use the 2!) not jump!
