The answers mentioned are mostly correct, I'd like to add some more points.
Digital communication:
Advantage:Digital instruments are free from observational errors like parallax and approximation errors.Can be noise-immune without deterioration during transmission and write/read cycle.
Analog Communication:
Advantage:Analog technology records wave forms as they are (continuous range of values to represent information). Hence more accurate.Analog signal processing can be done in real time and consumes less bandwidth.Low cost and portable.
