Telecommunication

Telecommunication is the assisted Transmission of Signal over a distance for the purpose of communication. In earlier times, this may have involved the use of smoke signals, Drum , Semaphore line, flag signals or heliograph....
s, transmission is the process of sending, propagating and receiving an analogue or digital information signal over a physical point-to-point or point-to-multipoint transmission medium
Transmission medium

A transmission medium is a material substance which can wave propagation energy waves. For example, the transmission medium for sound received by the ears is usually air, but solids and liquids may also act as transmission media for sound....
, either wired or wireless. Transmission technologies and schemes typically refer to physical layer
Physical layer

The Physical Layer is the first and lowest layer in the seven-layer OSI model of computer networking.The Physical Layer comprises the basic hardware transmission technologies of a network....
 protocol duties such as modulation
Modulation

In telecommunications, modulation is the process of varying a Periodic function waveform, i.e. a tone, in order to use that signal to convey a message, in a similar fashion as a musician may modulate the tone from a musical instrument by varying its volume, timing and Pitch ....
, demodulation
Demodulation

Demodulation is the act of extracting the original information-bearing signal from a modulated carrier wave.A demodulator is an electronic circuit used to recover the information content from the modulated carrier wave....

Equalization

Equalization, equalisation or EQ is the process of using passive or active electronic elements or digital algorithms for the purpose of altering the frequency response characteristics of a system....
, error control, bit synchronization and multiplexing
Multiplexing

In telecommunications and computer networks, multiplexing is a process where multiple analog message signals or digital data streams are combined into one signal over a shared medium....
, but the term may also involve higher-layer protocol duties, for example digitalization of an analog message signal, and source coding (compression).

Transmission of a digital message, or of a digitized analog signal, is known as data transmission
Data transmission

Data transmission is the physical transfer of data from point-to-point often represented as an electro-magnetic Signal over a point-to-point or point-to-multipoint communication channel....
 or digital communication.

One transmission is the sending of a signal with limited duration, for example a block or packet of data, or a phone call.
