Switching and amplifying current with transistors
Thinking logically with NAND gates
By now, you may be wondering if all that theoretical mumbo-jumbo discussed in Chapters 1–6 will really work in your very own home-grown electronics lab. Will your resistors really resist? When you charge up a capacitor, will it faithfully hang on to its electrical energy until you give it the go-ahead to discharge? Will your semiconductors actually conduct when you want them to? And are logic gates truly as logical as advertised?
If you’re interested in seeing the principles of electronics in action, then you’ve come to the right chapter.
In this chapter, we show you simple circuits that ...
