A simulation can tell the you within seconds if you are on the right track and how well the circuit performs.

The simulator can do it more accurately and faster than the reader. The philosophy of this book is to let a circuit simulator, such as one or the other of the freely available versions of SPICE, do the heavy lifting beyond the basic math. This is often a distraction and frustration for someone trying to learn about electronics and can cause them to lose interest in the topic. It is certainly important to understand the underlying fundamentals, but it can be tedious and time consuming for the reader to calculate every detail of a circuit. Traditional introductory text books on Electronics are often filled with detailed mathematical formulas which are used to explain the behavior of the electronic devices and circuits. Where possible the text and labs provide side bar links to more in depth background information for the more curious readers to explore. This book, through the extensive inclusion of laboratory activities, is an attempt at reviving the tinkering mentality that made electronics a popular career in the past, by making electronics concepts more accessible and giving practical knowledge, as well as providing underlying technical information for the reader. The treatment in this text is largely non-mathematical with strong encouragement of circuit brainstorming and mental estimation of circuit behavior and performance. For these reasons we have omitted entirely the usual in depth and detailed discussion of solid state physics, complicated network theory, and S-parameters. Electronics as, currently practiced, is largely a combination of some basic physical laws, rules of thumb and a large bag of tricks. Additional “advanced topics” are included in various chapters which can be inserted as desired. In this text we attempt to pull out and condense the amount of material and level of detail to an amount that can realistically be presented in the course of 20 or so 2 hour lectures and 10 2 hour Lab sessions.

Much of the more in depth subject matter, such as reference texts and professional journals, is now available electronically over the internet. Other authors have produced excellent examples of such texts.
This introductory Electronics I text is limited to the scope of teaching undergraduate EE students and is not intended to replace that all inclusive reference book on the art and science of Electronics. This motivation leads to books containing considerably more material in much greater detail than could be realistically covered in a one semester Introduction to Electronics course.
Typically authors of academic text books wanted their works to be considered the definitive reference for electrical engineering students and working engineers. Educational research has shown that humans retain as little as 10% of what they hear someone else tell them, but retain as much as 90% of what they learn by doing. Today, while students are computer-savvy, they exhibit a diminished attention span, and have multiple demands on their time. As a result, students have less “gut intuition” than prior generations possessed when entering the job market. Gone are the days when students entering college were ham radio operators, played with Erector sets and had tinkered extensively with electronic kits or simply taken things apart. One well known example is that interest in electronics as a hobby in the 1970s led to the creation of the personal computer.Īlthough they are extremely computer literate, today's engineering students frequently enter college without the same level of hands-on “tinkering” with hardware that prior generations exhibited. Interest peaked in the 1940s, 50s, 60s, with the invention of solid state devices, the transistor radio, the launch of NASA, and the educational push in math and science to win the space race. Broad interest in electronics started in the early 1900s with the introduction of radio communication and later broadcasting.
