Q. Show Benefits of digital systems?

Ever since most digital systems have only two possible states, there is high degree of accuracy in the transmission of data. With an analog system, information can take on an infinite amount of states. This is endless amount of possible states for analog information leads to possible errors in the transmission of that information. Digital systems are especially useful in the storage and transmission of audio and video information. After a period of time information that is stored in an analog form on a tape or record may degrade and loose its original fidelity. If that information is stored in the digital fashion, even if the data degrades or looses it value slightly, the reproduction of that information will still sound the same as long as the data still fall within the tolerances set for that type of information.
