Explanation: Morse code was designed so that the length of each symbol is inverse to the frequency of occurrence in text. Thus the letter in English, “E”, has a single dot.

Explanation: PARIS tells about word rate that is typical of natural language words and reflects the benefits of Morse code’s shorter code durations for common characters such as “e” and “t”.

Explanation: Morse code speed is measured in words per minute (wpm). The transmission rate of the Morse code is also measured is groups per unit (gpm).

Explanation: Morse code speed is measured in characters per minute (cpm) as well as in words per minute (wpm). The transmission rate of the Morse code is also measured is groups per unit (gpm).

Explanation: It was created by Friedrich Clemens Gerke in 1848 and initially used for telegraphy in Germany. Samuel Morse is the inventor of the telegraph after whom Morse code was named.

Explanation: The most common letter in English, the letter “E”, has a single dot. Morse code was designed so that the length of each symbol is inverse to frequency of occurrence in text.

Explanation: CODEX word offers a word rate that is typical of 5-letter code groups. PARIS is a standard word to measure the operator transmission speed of Morse Code.

Explanation: Prosigns are special unwritten procedural signals which are used to show changes in communications protocol status or white space text.

Explanation: Since the duration of Space Signal is equal to Dot Duration. So, the space signal is of 1 Unit. While a dash is 3 units and space between letters is also three units.

Explanation: The letters of a word are separated by a space of 3 Unit. The representation of dot symbol has 1 unit, while the dash symbol has 2 units.

Explanation: The symbol $ and & are not defined inside the ITU recommendation on Morse code. International Telecommunication Union is a union that mandated Morse code worldwide.

Explanation: There is no standard representation for the exclamation mark (!) in Morse code. The other symbols have been defined by the International Telecommunication Union.

Explanation: On May 24, 2004, the symbol @ was added to the official Morse character set by International Telecommunication Union.

Explanation: Iambic Paddle was used to generate high speed Morse Code in conjunction with an electronic keyer. It was commercially manufactured.

Explanation: Alfred Vail along with Samuel Morse developed Morse code. While Jedidiah Morse, Lucretia Pickering Walker were his father and spouse respectively.
