Have you ever wondered what makes you talk on your mobile phone? Did you wonder how the TV works? Did you want to know why a microwave oven is able to heat food so quickly? Or maybe you thought about how it is possible that a computer can handle data processing perfectly well? All this is possible thanks to electronics, a relatively young field of science that is wrongly considered to be complicated and difficult to master. To find out what makes the devices around us have specific properties, you need to learn about the principles of electronic circuits, and for this you need the right book.
In this role, the position "Electronic circuits in practice" will work perfectly. Its author presents in a very clear way the theory underlying the operation of several frequently encountered types of devices and presents methods of constructing such machines. By the way, he gives both lists of necessary elements and instructions on the assembly of individual systems. The book will show you how different types of generators, digital meters and radio receivers work, as well as learn how to build each of these devices yourself. If you want to get to know the practical side of electronics, and you already have basic knowledge about the theory behind it, it's just for you!
