Basic digital principles

YOU HAVE SEEN HOW DIGITAL SIGNALS DIFFER FROM ANALOG SIGNALS. THE manipulation of digital signals is called as digital logic. Digital logic consists of many at times innumerable pulses racing around. It can be staggering in the terms of quantity, but it is quite simple at heart: 1 or 0, high or low.

Assume that a few electronics engineers from, say, 1950 could ride a time machine to present day. They would be flabbergasted at speed and compactness of the digital logic circuitry. Some may be struck with disbelief. Others would say, I knew it would happen. And there would be the one who would quip.Well, digital logic circuits are becoming smaller, faster, and much sophisticated every day.
