This document discusses analog versus digital systems and the digital revolution. It notes that analog values are continuous while digital values are discrete. It gives examples of analog clocks and temperature measurements versus digital clocks. The document then discusses how many devices have been converted from analog to digital, including record albums to CDs, VHS tapes to DVDs, and analog TV to digital TV. Finally, it explains how systems like CD players use both analog and digital components, taking digital data from the CD and converting it to an analog audio signal for playback.

Analog versus Digital Analog = continuous Digital = discrete Example: • An analog clock, whose hands move smoothly and continuously. • A digital clock, whose digits jump from one value to the next.
