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.
Transmission system technologies typically refer to physical layer protocol duties such as modulation, demodulation, line coding, equalization, error control, bit synchronization and multiplexing, but it may also involve higher-layer protocol duties, for example, digitizing an analog signal, and data compression.
Transmission of a digital message, or of a digitized analog signal, is known as data transmission.
Examples of transmission are the sending of signals with limited duration, for example, a block or packet of data, a phone call, or an email.
