How this information is transformed depends upon its original format and on the format of the communication hardware. Introduction. If you want to send a letter by a smoke signal, you need to know which smoke patterns make which words in your message before building the fire. Gradients. Slice selection. Frequency encoding.

Method used to encode information in terms of signal transition. The original binary information is recovered simply by comparing the polarity of adjacent binary symbols to establish whether or not a transition has occured. Pat Nicholson* and Rajeev Raman**. *.

Chapter 5. “Thus one says, in general, that the function of the transmitter is to encode, and that of the receiver to decode, the message. The theory provides for very sophisticated transmitters and receivers—such, for example, as possess ‘memories,’ so that the way they encode a certain symbol of the message depends not only upon this one symbol but also upon previous symbols of the message and the way they have been encoded.”.
