Morse code is one type of communication techniques that uses clicks, on off tones and lights to transmit textual information. The transmitted message can be understood and interpreted by a person who has background and decoding skills of this method.

Dits and dahs or dots and dashes respectively are used to represent characters such as letters and numerals. Three dots represent the space separating each letter of one word. Meanwhile, seven dots also represent the space that separate one word from another.

When it comes to speed measurement, this is typically measured in characters per minute or words per minute. The lengths of the words and characters would vary as this will depend on the dits and dahs. Coding efficiency is one feature which is very important in this method.

Extensive use of this technique began in the 1890s where it was commonly used for early radio communication. A this point in time, voice transmission was not yet possible which lead people to make use of these communication signals instead when transmitting messages.

This method has an advantage to offer has it can be used or transmitted by radio waves in conditions where there is poor signal. This technique makes a good replacement as voice communication would not be possible in these conditions. This will be useful in emergency situations.

Due to this reason, this system is seen as a good alternative for synthesized speech. It is possible to send digital data which will be interpreted by a skilled listener. It may be a simple method of telecommunication but it has helped many different sectors.

A number of industries still make use of Morse code today. These include the field of aviation, air traffic controllers and most especially amateur radio operators. This is also used by the general public during emergency cases. Individuals with certain disabilities can also make use of this. Morse Code
