In such instances decoding involves complex methods that are used to filter out the effect of noise in the message. But decoding messages sent via a noisy channels will not be straight forward, because the message could be tampered with noise. For example, ASCII encoding is just a mapping between characters and numbers. Encoding is done using publicly available methods and it can be easily reversed (decoded). Encoding is done with the intension of increasing the usability of data in different systems and to reduce the space required for storage, while decoding converts encoded information back in to its original format. What is the difference between Encoding and Decoding?Įncoding and decoding are two opposite processes. Decoding methods such as Ideal observer decoding, maximum likelihood decoding, minimum distance decoding, etc are used for decoding messages sent via noisy channels. This process is not straight forward as the previously mentioned decoding schemes, since the message could be tampered due to the noise in the channels used for communication. In the filed of communication, decoding is the process of converting received messages in to a message written using a specific language. The term decoding is also used for digital to analog conversion. Decoding ASCII values is a straightforward process since there is a one to one mapping between characters and numbers. For example, decoding Binary Coded Decimal requires some simple calculations in base-2 arithmetic. Encoded data can be easily decoded using standard methods. The term encoding is also used for analog to digital conversion.ĭecoding is the reverse process of encoding, which converts encoded information back in to its original format. For example, Binary Coded Decimal (BCD) encoding system uses four bits to represent a decimal number and Manchester Phase Encoding (MPE) is used by Ethernet to encode bits. Encoding techniques are also used when transporting data. Compressing data can also be seen as an encoding process. Similarly, encoding systems such as DBCS, EBCDIC, Unicode, etc. For example, you may realize youre hungry and encode the following message to send to your. The encoder uses a medium to send the message a phone call, email, text message, face-to-face meeting, or other communication tool. ‘A’ is represented using number 65, ‘B’ by number 66, etc. What is encoding in communication with examples Encoding is the process of turning thoughts into communication.
DECODING IN COMMUNICATION CODE
For example, in ASCII (American Standard Code for Information Interchange) characters are encoded using numbers. Most of the time, the converted format is a standard format that is widely used. Transforming data in to more usable formats for different systems, using a method publicly available is called encoding. Decoding is the reverse process of encoding, which converts encoded information back in to the original format. It is also used for reducing the storage space required to store data and for transferring data across different channels. The purpose of this transformation is to increase the usability of data especially in different systems. Results were as follows: (a) the ability to encode and the ability to decode both visual and auditory cues were significantly related (b) the relationship between encoding and decoding cues of the same emotion appeared low or negative (c) the ability to decode visual cues was significantly related to the ability to decode auditory cues, but the correlations among encoding (and decoding) scores on different emotions were low (d) females were slightly better encoders, and significantly better decoders, than males (e) acquaintance between sender and judge improved decoding scores among males but not among females (f) auditory decoding scores were higher than visual decoding scores, particularly among males (g) auditory decoding scores were relatively high if sender and judge were of the same sex, while visual decoding scores were relatively high if sender and judge were of opposite sexes (h) decoding scores varied according to channel of communication and type of emotion transmitted.Encoding is the process of transforming data in to a different format using a method that is publicly available. These expressions were recorded and presented for decoding to the senders and an additional group of judges. Subjects ("senders") encoded six emotions twice, first via facial expressions and second via tone of voice.
