Everything becomes Digital – Really Everything?

Abstract

When Mrs. Miller complained, “In our area, cable TV service was converted to digital, and therefore we had to rent a converter box,” she probably believed that digital technology is something quite new which didn’t exist twenty years ago. And if I had asked her what she knows about digital systems, she might have answered, “That’s a kind of electronics with only zeros and ones.” Although this answer is actually correct with respect to over 99 percent of today’s digital systems, it’s not a correct definition, nevertheless. A digital system does not necessarily need to be implemented electronically or to operate with zeros and ones.
