The transmitter is an electronic component that converts the digital signal from the encoder into an analogue signal that can travel through the wire and be heard by the receiver. The transmitter is sometimes referred to as the modulator. The range or distance that the signal can travel through the wire is limited by the audio properties of the wire. The transmitter also adds additional information to the signal, such as channelization codes, to allow the receiver to correctly identify which channel it is receiving.
Position of Transmitters in a Communication System
Information can be sent over a communication system from either a person or a machine. In a communication system, a transmitter is positioned at one location and a receiver is placed at another location, with the channel serving as a medium between the two locations. When the message signal originates from the source, it is used to feed into the transmitter.
The signals that are conveyed are referred to as transmitted signals. Transducers transform non-electrical signals into electrical signals when the message signal from the source of information is nonelectrical.
The physical media that links the transmitter and receiver (whether wired or wireless) is the channel. It is possible that the broadcast signal may be warped due to its imperfection and that some noise will be added to the transmitted signal as it propagates.
Transmitter as a Component of the Communication System
An in-depth examination of the components of the communication system. Information is the concept or message that is being given. It is also known as knowledge. The message may consist of a single message or a series of messages. The message might take the form of a symbol, a code, a sequence of words or any other predetermined unit.
A transducer, modulator, amplifier and transmitting antenna are all transmitter components in radio transmission. Transducers are also known as transmitters.
- A transducer is an electronic device that transforms sound waves into electric signals.
- An audio modulator is a device that combines an electric audio signal and a high-frequency radio wave.
- The modulated signal is amplified by the amplifier, which increases its power.
- With the help of an antenna, the signal is broadcast into the surrounding space.

It is the responsibility of the communication channel to transport the modulated signal from the transmitter to the receiver. Communication channel definition: The communication channel is sometimes referred to as a transmission link or a medium of transmission.
In radio communications, the phrase “channel” refers to the frequency band that has been assigned to a particular broadcast or service.
The communication system is a system of communications equipment, cables and other components that transmit signals, such as telephones, television and radio. The purpose of a communication system is to transmit signals from one place to another. The first communication systems were signal fires, smoke signals and drums.
Modern communication systems use electrical wires and radio waves. Communication systems are the means by which people, animals and machines exchange information. There are many different forms of communication systems, such as human language, animal signals and electronic communication. All communication systems share a basic structure. They all have a sender and a receiver and they all convey a message from one person or thing to another.
Types Of Communication Systems
Communication systems are divided into two categories: Analog and digital.
- Analogue: Analog technologies transmit data between people or machines as electronic signals of various frequencies or amplitudes. Telephone and radio transmission are the most common examples of Analog technology.
- Digital: Digital technology, information is generated and processed in two states: high and low. Digital technology stores and transmits the data in the form of 0s and 1s.
There are two types of communication channels:
- Wired: In wired communication, it is of 4 types:
Parallel wire communication
Twisted wire communication
Coaxial cable communication
Optical fibre communication
Wired communication is also known as line communication.
- Wireless: In this, there are 4 types of communication:
Ground wave communication
Space wave communication
Wireless communication is also known as space communication.
Types of Communication Systems: Data communication
Communication modes are categorised as follows:
Point to point: The transmission of information from one location to another is known as point-to-point communication (P2P). When a single transmitter and receiver communicate, this is called asynchronous communication.
Broadcast: Although a single transmitter provides the information, many receivers are broadcast. Television and radio are both broadcast methods of communication systems.
Communication system examples:
- Public Switched Telephone network
- Intranet and Extranet
Various elements of communication system:
Signal: The single-valued function of time which carries the various information, which is then converted into electrical form, so that it can be transmitted.
Amplifier: The electronic device or circuit that increases the strength or amplitude of signals received by a device and which can be done anywhere from the transmitter to the receiver.
Communication is the exchange of information and ideas between people. The basic elements of communication are signals— speech, text and body language and the meaning that is shared between the sender and the receiver. Communication can be defined as the exchange of information and ideas between people through a variety of methods, such as speech, text or body language. The meaning that is shared between the sender and the receiver of a message is the meaning that is understood or inferred from the message.
