Answer 1

Digital ControlAnalog ControlAdvantagesNo signal losses due to DA and AD conversionGeometry, clock and phase settings unnecessary, therefore simple to useLower costs as less electronic circuitry requiredCompatible with standard VGA boards on a broad installed PC basisNot necessary to purchase a new graphics board

Answer 2

There are none except for the fact if the if the input signal has variations in value, with no filtering, the digital readouts can become a guess to read.

Analog meters will average these variations as a wiggle of the needle so that the reading changes in a slower manner which is easier to read.
