An amateur person may need a few seconds to transmit a single character, a skilled professional can transmit 60 words per minute, and robotic transmitters may go way faster.įor this kata we assume the message receiving is performed automatically by the hardware that checks the line periodically, and if the line is connected (the key at the remote station is down), 1 is recorded, and if the line is not connected (remote key is up), 0 is recorded. And in fact different operators would transmit at different speed. However, the standard does not specify how long that “time unit” is. Pause between words – is 7 time units long. Pause between characters inside a word – is 3 time units long. Pause between dots and dashes in a character – is 1 time unit long. When transmitting the Morse code, the international standard specifies that: The Morse code encodes every character being transmitted as a sequence of “dots” (short presses on the key) and “dashes” (long presses on the key). In this kata you have to write a Morse code decoder for wired electrical telegraph.Įlectric telegraph is operated on a 2-wire line with a key that, when pressed, connects the wires together, which can be detected on a remote station.
