Abstract
When I was considering the question posed, my immediate thought was that of course reality is analog. There are many visible, quantifiable and provable examples of this. Among them are the examples of the first and the latest digital-to-analog (DAC) converters and their counterparts the analog-to-digital converters (ADC). Several of the companies for which I have worked produced products that processed signals. The goal in producing these devices was twofold: First, reduce or eliminate noise and; Second to digitally represent the analog signal as closely as possible. I remember the first 8-bit DACs and how proud the developers were of their achievement. I also remember 128-bit converters and how, over the years, the engineers (or more correctly the marketing departments) would brag about this continuing achievement.
