In telecommunications, transmission (sometimes abbreviated as "TX") is the process of sending or propagating an analog or digital signal via a medium that is wired, wireless, or fiber-optic.
The origin of the words transmit and transmission and their derivatives go back to the Latin word , in turn formed by prefixing the preposition trans (âÂÂacross or beyondâÂÂ) and the verb mittere (âÂÂto let go or to sendâÂÂ).
Signal transmission is the process of transferring information from one point to another, through different communication systems. These can be: electrical signals, optical signals, radio waves, or other forms of energy.
