An example of a variable-length code is Morse Code, developed for the telegraph. The codes for letters, digits, and punctuation are sequences of dots and dashes with short-length intervals between them. See Section 2.9.
The decoder tells the end of the code for a single character by noting the length of time before the next dot or dash. The intra-character separation is the length of a dot, and the inter-character separation is longer, the length of a dash. The inter-word separation is even longer.
