What do we study in electronics and communication engineering?

We will begin by studying the basics of electrical engineering (different types of circuits, laws, power generation and transfer), and then move on to the fundamental element of electricity, the electron. This is how we can manipulate electrons and holes (absence of electron) to create different devices such as transistors, diodes, Op-amps, and so forth.

All of the above are covered under the headings of Electronic networks, electronic devices and Analog circuits. Linear integrated circuits is another example.

There are also digital electronics, micro processors and controllers.

This section explains how digital devices store data and how it is processed. This is how a computer works (cpu to be exact) on the most basic hardware level. What are the associated circuits and devices for efficient operation (RAM, ROM multiplexers, registers, flip flops,ADC,DAC?

We can then see how electricity can be represented using mathematics as signals.

This is what we refer to as Signal Processing

What are the different types of signals and systems? Systems are mathematical models of any device or environment. How do signals move through different systems?

There are also extensive mathematical analyses on how stable a system is and how it responds. This will be dealt with again in Signal Processing, and more extensively in Control Systems

We also know how electricity leads to electron movement, which creates current and magnetic field. Then we can see how these changing fields produce EM waves. How the EM waves behave in different media

This is a result of Electromagnetic Wave Theory, Wave propagation, and others

These devices will be used or the principles that we have studied to ensure efficient data transfer over long and short distances. What devices generate these EM waves? How data is securely transmitted?

These will be used in Analog, Digital communication and Antenna.

You might also be able to learn programming languages such as C, Java, Computer Organization, Computer Networks and Computer Organization depending on your university curriculum.

There are also advanced communication subjects such as television engineering, satellite communication, mobile communication, internet communication, and so on.

Also, we have advanced subjects such as Image, Video and Speech Processing, and also related subjects like Data compression, Encryption, and Encryption.

If you’re really interested in learning this interesting stuff, then you are most welcome to join the EC community :).


The EC coursework also includes VLSI Design basics.

You will encounter design problems in many subjects, not just analytical ones. This design aspect makes engineering degrees unique and fascinating.

P.S. A disclaimer,some universities/institutes in India don’t take the “learning practically” way seriously and just focus on keeping the course exam oriented . This is a disservice to the purpose of this course. Anyone considering the course should not expect too much and instead learn new skills to make them more employable in their core industry.
