An '''analog''' system is a [[mathematics|mathematical]] system in which numbers vary continuously instead of shifting between discrete states as a [[digital]] system does. For example, in an analog clock, the hour, minute, and second hands all move continuously. Halfway between 2:00 and 3:00, the hour hand will be pointing halfway between the 2 and the 3. In a digital clock, the numbers simply shift between discrete states: halfway between 2:00 and 3:00, the hour digit will still read 2. | An '''analog''' system is a [[mathematics|mathematical]] system in which numbers vary continuously instead of shifting between discrete states as a [[digital]] system does.
