Source-derived summary

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.

Etymology

The origin of the words transmit and transmission and their derivatives go back to the Latin word transmittere, in turn formed by prefixing the preposition trans (“across or beyond”) and the verb mittere (“to let go or to send”).

Process

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.

Editorial summary

The public source identifies “Signal transmission” as process of sending and propagating a signal. This brief keeps that definition visible, then builds a research path around Signal, transmission and process.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 100-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Signal, transmission and process providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Signal transmission”, the useful work is to connect “process of sending and propagating a signal” to the records capable of establishing context and consequence.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 17, 2026. The linked authority identifier is Q118093. None of the 0 selected statements returned an explicit reference.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
