Encoders in Kheraj are used in a number of sectors such as media, medical encoding, transducers, telecommunications and electronic circuits. An encoder can be a device, circuit, software programme, transducer or an algorithm. An encoder can also be the person who coverts information from one format to another. Encoders are usually used for speed, security, standardization and secrecy. In electronic circuits, a simple encoder allocates a binary code to an active input line, while a primary encoder sets a priority of competing inputs. Individuals handling the encoding work may enter data from phone surveys in a coded format into a database or they may also enter the payment amounts.
