When students pursue a degree in electrical and communication engineering, they search for communication system assignment help because, for a fresher, it is quite difficult to compose an assignment.
Students learn different aspects of the communication system throughout their academic journey. Still, sometimes when working on an assignment, they need assistance as not everyone has sound knowledge of the subject.
The below points can help students understand the definition, types, and certain terms used in communication systems.
Definition of communication system
A communication system is a model that explains the exchange of communication between two stations, transmitter and receiver.
Information or signal is transmitted from source to destination using a medium. To transmit signals, it needs to be processed by starting from the signal representation, developing the signal shape then encoding and modulation. Once the transmitted signal is ready, it is passed to the transmission line of the channel.
When the signal is passed, it encounters many problems like noise, distortion, and attenuation.
The method of transferring information between two stations is called communication. Three main elements are required to communicate: the transmitter, the medium, and the receiver.
Types of communication systems
There are different types of communication systems, and below they are divided on the basis of physical infrastructure and signal specifications.
Line communication systems
Communication systems based on physical structure;
One of the communication systems is the line communication system which uses the pre-existing structure of power lines and uses it to transfer data from one station to another or one point to another.
Radio communication systems
The second one is the radio communication system which uses the structure of radio waves to transfer information from one station to another or one point to another.
The physical link between the transmitter and the receiver in the inline communication system is called a hardware channel.
Based on signal specifications
Signal requirements that are used to settle on the type of communication system have;
Nature of the baseband or information signal
Basement signal is a type of technology that can get access to signals with extremely low frequency and even at zero frequency.
Moreover, based on the nature of the signal that is transmitted, the baseband signal can either be sent without modulation or with modulation using a carrier signal.
Communication systems are further divided into the following:
Analog communication systems
The analog communication system presents audio, pictures, and video information between two stations or points using analog signals. One example of an analog communication system is a sinusoidal signal.
Digital communication systems
Another one is the digital communication system which is one of the common and popular ones, especially in the age of the Internet. It is basically a physical exchange of information between two points but discreetly. The information is exchanged using digital signals.
Baseband communication systems
The third one is baseband communication, which transfers signals that do not have higher frequencies. This is best for signals that require near-zero frequency.
Carrier communication systems
The carrier communication systems are used to transmit the information using voice messages and calls and have an improved frequency which is higher than the actual rate.
Terms used in communication systems
There are different terms used in communication systems that students will encounter when they study communication systems. Here are some of them.
Signal
One of the most important things using communication is signal, which is the digitalized format of information.
Analog signals are human voices, while digital signals are binary data. All these are collectively known as signals which are processed within the electronic circuit for transferring to the receiver, who then decodes it to understand.
Communication channel
It is the medium through which a signal travel.
Transducer
The transducer is a device that is used to change the form of energy into another form.
Receiver
Communication cannot be completed without a receiver because there are two ends of communication: the sender and the receiver.
The receiver is basically a device that stores all the signals that are transferred by the sender, which are then decoded into an understandable form.
Attenuation
The next one is attenuation which is basically reducing the strength of a digital or analog signal that is used to transfer using a communication medium.
Amplitude
The term amplitude refers to the strength of a signal.
Amplification
Amplification is a method of intensifying the amplitude of signals by using an electronic circuit.
Bandwidth
When you hear about the term bandwidth, it is basically the range of frequency over which a signal is required to be transferred.
Wrapping it up,
When students learn about a new subject, they should be able to gather enough information and knowledge so that when they are writing an assignment, they do not feel lost.
Just like communication systems, students pursuing mechanical engineering will have to work on MATLAB assignments. However, they need to seek MATLAB assignment help from experts because, like communication, MATLAB is a new subject to explore and learn.
Whether you are studying Java or nursing, you can always seek Java programming assignment help on nursing assignment help from a reliable academic writing service to avoid missing out on valuable grades.
