Keep This Frequency Clear

Telecommunication is information transmitted over significant distances to communicate. In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages via coded drumbeats, lung-blown horns, or sent by loud whistles, for example. In the modern age of electricity and electronics, telecommunications now also includes the use of electrical devices such as telegraphs, telephones, and teletypes, the use of radio and microwave communications, as well as fiber optics and their associated electronics, plus the use of the orbiting satellites and the Insidious Internet.

INFOCO: DIGAMMA

This day we are discussing the Ancient Greek Letter Previously known as Digamma.
today known as
The alphabet is a set of letters or characters representing sounds. It is used in writing a language. The word is derived from “alpha” and “beta”, the first two letters of the Greek alphabet. The English language uses the twenty-six letter alphabet, called the Roman. It is however interesting to note that the Romans were not the original inventors of the English alphabet; they merely improved upon a system of writing that was already in existence for thousands of years.
regarding the so called Latin_script
also important knowledge is the names of letters: 
 Phoenician letter names, in which each letter was associated with a word that begins with that sound, continue to be used to varying degrees in Samaritan, Aramaic, Syriac, Hebrew, Greek and Arabic. The names were abandoned in Latin, which instead referred to the letters by adding a vowel (usually e) before or after the consonant (the exception is zeta, which was retained from Greek). In Cyrillic originally the letters were given names based on Slavic words; this was later abandoned as well in favor of a system similar to that used in Latin.

The Digamma Today: F


The origin of ⟨f⟩ is the Semitic letter vâv (or waw) that represented a sound like /v/ or /w/. Graphically, it originally probably depicted either a hook or a clubThe Phoenician form of the letter was adopted into Greek as a vowel, upsilon (which resembled its descendant, ⟨Y⟩, but was also ancestor to Roman letters ⟨U⟩, ⟨V⟩, and ⟨W⟩); and with another form, as a consonant, digamma, which resembled ⟨F⟩, but indicated the pronunciation /w/, as in Phoenician. (After /w/ disappeared from Greek, digamma was used as a numeral only.)
In Etruscan, ⟨F⟩ probably represented /w/, as in Greek; and the Etruscans formed the digraph ⟨FH⟩ to represent /f/. When the Romans adopted the alphabet, they used ⟨V⟩ (from Greek upsilon) to stand for /w/ as well as /u/, leaving ⟨F⟩ available for /f/. (At that time, the Greek letter phi ⟨Φ⟩ represented an aspirated voiceless bilabial plosive /pʰ/, though in Modern Greek it approximates the sound of /f/.) And so out of the various vav variants in the Mediterranean world, the letter F entered the Roman alphabet, which forms the basis of the alphabet used today for English and many other languages.
The lower case ⟨f⟩ is not related to the visually similar long s, ⟨ſ⟩. The use of the long s largely died out by the beginning of the 19th century, mostly to prevent confusion with ⟨f⟩.
Of course theres also Roman_numerals which however we will discuss a bit later.
and there's our follow up on the history of the English Alphabet.
The English alphabet developed from a number of early writing systems. The Romans had given most capitals their modern form by A.D.114. But the letters J, U and W were not added to the alphabet until the Middle Ages.  
With that action, again the calculation is further sealed for a latter time.
what does it all mean ?
lets bring in numerals ok.
