How many symbols are there in a coding system?
The number of different symbols q, employed by a coding system, can vary greatly, and depends strongly on the purpose and the application. In computer technology, only two switch positions are recognized, so that binary codes were created which are comprised of only two different symbols. Quaternary codes, comprised of four different symbols, are involved in all living organisms. The reason why four symbols represent an optimum in this case is discussed in chapter 6. The various alphabet systems used by different languages consist of from 20 to 35 letters, and this number of letters is sufficient for representing all the sounds of the language concerned. Chinese writing is not based on elementary sounds, but pictures are employed, every one of which represents a single word, so that the number of different symbols is very large. Some examples of coding systems with the required number of symbols are:
What is the choice of code?
The choice of code depends on the mode of communication. If a certain mode of transmission has been adopted for technological reasons depending on some physical or chemical phenomenon or other, then the code must comply with the relevant requirements. In addition, the ideas of the sender and the recipient must be in tune with one another to guarantee certainty of transmission and reception (see Figures 14 and 15). The most complex setups of this kind are again found in living systems. Various existing types of special message systems are reviewed below:
Which theorem states that only structures based on a code can represent information?
