The advantages of digital
Analog communication stands for transaction of analog signal. Digital communication stands for transaction of analog signal. Digital communication stands for digital signal as carrier for traction.
Advantages
Strong capability of Anti-interference
Analog signal is very difficult to separate to the noise signal when it is transformed, the noise signal will be enlarged during the process of transaction, it will influence the quality of the transaction of the signal. But digital signal contain the information in 1 and 0, the receiever can easily diagnose the correct signal if the noise would not exceed the power of 1 to ensure the quality of transaction.
Able to afford long distance transformation
Digital signal adopt re-continuing to reduce the noise during the transformation procedure, so the signal after long distance still remain the same as original one, and it can also accept telephone, telepraph, image and data, so the digital service can support systematical data network, it makes the MMIC possible to support the encryption and enhance the computer management.
