Certain types of information can only be transmitted after encoding. In the best known encoding procedure, the Morse code, every letter in the alphabet is presented by a sequence of short and long signals (dot/dash or long tone/short tone). Morse messages are still transmitted in short and long tones.
The recording of a SOS Morse message underscores that individual coded signals (three short, three long and three short sounds) convey information: SOS = "Save Our Souls".
