More Info
Engineers build the foundation for solid and secure systems that we all use every day. The number of facts needed for those calculations is staggering and just one mistake can wreak havoc. This must-have reference to the core fundamentals of electronics is perfect for any student or professional. Concisely written so you can have more answers in 6 durably laminated pages than you would find in 100 pages of a book. Ready at your fingertips for studying and boosting grades, or for career projects in the working world providing one more verification of facts that can ensure a solid build. Concepts covered are taught in electronic circuit courses for engineers where key facts learned need to be referenced throughout engineering school and a career. With the number of facts covered and the durability to last a lifetime, there is also no better value. To complete the set, get Electronics 1 & Electronics 2 for even more well-rounded coverage.
