Analog is like me screaming after 50 meters on a windy day a different person to say that football is good, and try to understand.
Digital is as if football is written on a sheet of paper and a person at 50 meters, then the person who reads and understands.
If you write that 50 meters from the person poorly understood and can not hear the entire message.
When you write, and get them to understand the message and do not miss anything.
Devices are worn to emit radio waves. Used digital ones and zeros instead of words.
The benefit is from analog to digital is almost dead, almost everything that is digital now, I would not worry about analog.
Analogue TV transmissions use a range of frequencies to transmit what he interpreted as a TV picture and sound. Digital TV image and converts the sound into 1s and 0s (digital information) and then transfer these impulses in a very narrow frequency range. This means that holds in the transmission of digital wireless much less spectrum than analogue. This is the primary reason why the United States and other countries changed their programs in digital. She has published a large part of the radio waves to other things.
The type of digital transmission is also more resistant to interference cleaner, look like digital television.
The only advantage is that analog is technically simpler. With the power of certain digital computer is necessary to convert 1s and 0s back into pictures and sound. Insignificant in comparison to modern standards, but then do not forget that there is no electronic calculator ... not even the size of the bank ... when television first introduced.
Digital is better. And only for a school project, ask your own research.
