I grew up on Star Trek. Captain Kirk and his valiant crew sparked my imagination as they journeyed through the galaxy on their amazing adventures. So it’s only logical that I’m inclined to begin a chapter on logic with a reference to Mr. Spock. In fact, it would be illogical to begin this chapter in any other way.
In this chapter, I look at the basic principles of logic, which are the underpinnings of digital electronics. In particular, I explore logic gates, which are handy devices that perform a logical operation on two binary inputs and produce a single binary output result.
It’s incredible to realize that the overwhelming complexity of modern computer systems is built on the simple concept of logic gates. A modern ...
