Braille pattern dots-26 Braille pattern dots-26 The Braille pattern dots-26 ( ) is a 6-dot braille cell with the middle left and bottom right dots raised, or an 8-dot braille cell with the upper-middle left and lower-middle right dots raised. It is represented by the Unicode code point U+2822, and in Braille ASCII with the number 5. In unified international braille, the braille pattern dots-26 is used to represent an unrounded open-mid to close-mid front vowel , such as /e/, /e̞/, or /ɛ/ when multiple letters correspond to these values, a question mark, or is otherwise assigned as needed.

Morse code and Channel Coding comparisons, the word "PARIS" is used to determine Morse Code's properties because it has an even number of dots and dashes. Morse Code, when transmitted essentially, creates an AM signal (even in on/off keying mode), assumptions about signal can be made with respect to similarly timed RTTY signalling. Because Morse code transmissions employ an on-off keyed radio signal, it requires less complex transmission equipment than other forms of radio communication. Morse code also requires less signal bandwidth than voice communication, typically , compared to the roughly 2400 Hz used by single-sideband voice, although at a lower data
