What is Transmitter definition/concept

The term transmitter is polysemic, it has several different meanings depending on the context used. The world of communication refers to devices that transmit a message to its receiver through a channel, for example, a satellite dish or a mobile telephone terminal. In economics, the transmitter is called the issuer: the individual or entity that puts bonds, securities and notes into circulation. While in mechanics the term transmitter is used to designate the connectors that put into operation a device.

The transmitter as a communication element

Furthermore, all the meanings of transmitter refer to its function as one of the factors of communication.

The communication process always has by definition two parts involved: the presence of someone who transmits the message (the sender) and the one who receives it (the receiver). Linguistic theory advocates that every communicative process, whatever the channel used (speech,  writing, sign language, etc.) is composed of 8 steps, 3 of which correspond to the sender.

The transmitter is responsible for starting the communication process: creating a message and sending it to the receiver

In turn, it will analyze the information and reconstruct the message. Once the message is synthesized and its meaning constructed, it will become a sender from the moment it responds to the message sent.

For this entire process to be carried out satisfactorily, it is essential that the transmitter (sender) and the receiver have the same language system , for example, that they speak the same language, so that the messages sent to the transmitter can be understood by the receiver . In addition, the words must be sent through an appropriate information channel (oral or written) which may vary depending on the type of communication established by the parties involved.

And finally, it is worth noting that in everyday life, everyone plays the role of transmitter or receiver at some point and that these roles change naturally.

coded transmitters

In certain situations it is possible that the transmitter and receiver limit access to the information they are receiving, which is why encoding is used . Currently, this process is common in satellite television, where some channels emit an encoded signal that can only be accessed through a specific decoder. Historically, the most famous case was the Enigma machine, used by the Nazi army in World War II, to prevent its messages from being sent to the allies so that they could not understand what was being said.
