How to reference this medium
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".
Information and ideas:
Ideally suited as entry to the topic area of coding, speech, communication.
