ABSTRACT
As we wrote in the introduction to this book, one hears the term "digital" expressed all the time, often paired with nearly every conceivable device and action of daily life. So much so that by now, the term may seem a bit buzzy or even annoying to many. However, in our treatment, we have deliberately chosen to refer to digital in its most fundamental sense:
" .. .in contrast to the continuous and variable analog world of human experience, digital is finite and non-variable. It utilizes discrete data points that are either on or off, ones or zeros. As such, digital is the language of the computer in its many forms."
