About this Book:

Amplitude-modulation (AM) radio building has always been an interesting area amongest electronics hobbyists. This book can be used as a complement to textbooks for circuits classes and lab courses. From basic stuff to DIY projects the goal of this book was to design as many new or unconventional circuits as possible, along with some conventional examples. Any or some of these circuits can be used for teaching a laboratory electronics class in college and, to some degree, even in high school.
