It is during this conversion process that information can be lost. Depending on the process digital doesn't always capture all the gradations in analog data.

WIth a digital clock you can only ever see the exact minute 12:01am or 12:02am. The digital information doesn't show you the time between 1 minute past and 2 minutes past. But with an analog clock the minute hand is always moving. At halfway between 12:01 and 12:02 the minute hand will be halfway between the 1 and the 2 minute mark. If you look closely you will be able to see that it's halfway between.
