Digital Encoding of Information

Posted 10:03 PM by Sobia in Labels: ,
Data and messages can be processed digitally, by encoding them into binary digits. Each piece of information must be converted into a binary unit using an unambiguous code scheme. This process is also called data encoding. Effective data processing is only possible if cooperating computers and programs all use the same codes. Analog information is highly liable to interference and errors are caused by even the smallest –disturbance signals, but digitally encoded information will only be distorted when the disturbance signal is larger than the signal-to-noise ratio of the digital level used. 

Digital encoding has the following advantages:
  • High interference immunity
  • Easy data storage
  • Flexible processing 
  • Various transmission options
