You press the microphone button on your phone in Kolkata and say, “I’ve arrived. Rohit calls after dinner.” A few seconds later, someone in Bengaluru hears your voice.
That simple voice note passes through several engineering stages. Each stage has a specific role, and electronics and telecommunication engineers help make it all work.
This guide covers the subjects you’ll study, the practical skills you’ll need, how to compare university syllabi, and the career paths you can pursue after graduation.
What is Electronics and Telecommunication Engineering?
Electronics and telecommunication engineering connects two closely related fields. One deals with the electronic circuits that process signals; the other focuses on transmitting those signals from one place to another.
Look at how a voice note travels from your phone in Kolkata to someone in Bengaluru.
- Your voice becomes an electrical signal.
- The phone converts the signal into digital data.
- The phone adds extra data to help detect and correct errors.
- A radio wave carries the data.
- The phone prepares the signal for transmission.
- The antenna sends the signal through the air.
- A cell tower receives the signal and forwards it.
- The network routes the data to its destination.
- The receiving phone converts the data back into sound.
Several technologies work together to make this possible. Electronics involves creating, processing, and reading electrical signals. Telecommunication focuses on transmitting information over long distances. In the graduation, you’ll study how these systems work in detail through subjects.
ECE, E&TC and EXTC: What’s the Difference?
Electronics and telecommunication engineering goes by different names at different institutions.
SPPU in Pune and Shivaji University in Kolhapur use E&TC, ETC or ENTC for Electronics and Telecommunication Engineering. Mumbai University uses EXTC, while BITS Pilani and Thapar use ECE. So, different universities use different titles and abbreviations for the course.
The names also differ across competitive examinations. GATE uses Electronics and Communication Engineering (EC) for its paper. The UPSC uses ET (or E&T) for Electronics and Telecommunication Engineering in the examination.
Most curricula across all three branches often overlap, but the exact syllabus varies by institution. Before choosing a college, download its official syllabus and compare the subjects, laboratory work and electives.
How to Get Into Electronics and Telecommunication Engineering?
Electronics and telecommunication engineering is a four-year undergraduate degree offered as a BE or BTech programme across eight semesters. You need to have studied Physics, Chemistry and Mathematics in Class 12. The minimum aggregate marks vary by college and its admission rules.
| Admission Route | Details |
|---|---|
| After Class 12 | JEE Main, JEE Advanced, state-level entrance exams and institute-level exams such as BITSAT and VITEEE. |
| Diploma holders | May be eligible for lateral entry into the second year, depending on the institution’s rules. |
Electronics and Telecommunication Engineering Syllabus
Most universities follow a common foundation for the programme. The order and names of subjects can vary by university. Check your university’s latest syllabus to see which subjects are taught in each semester.
Years 1 and 2: Building the Foundation
Year 1 covers engineering mathematics, physics, basic electrical and electronics, C programming, and engineering graphics. Mathematics is particularly important. Calculus and linear algebra return as Fourier transforms in the signals course and as Maxwell’s equations in electromagnetics.
In some colleges, electromagnetics generally arrives in Semester 3, and sometimes it appears in Semester 5.
Year 2 builds on these fundamentals with network theory, analogue circuits, digital circuits, linear integrated circuits (ICs), signals and systems, control systems, introductory communication, and microcontrollers.
Year 3: Core Subjects and Communication Systems
Year 3 builds on the fundamentals and introduces more specialised subjects. Common subjects include Digital Communication, Electromagnetic Field Theory, Antennas and Wave Propagation, Computer Communication, Digital Signal Processing (DSP) and Embedded Systems and Microcontrollers. Students may also begin choosing electives based on their interests.
Year 4: Specialisation and the Final Project
The final year explores advanced topics and allows students to apply their knowledge through a project. Subjects may include VLSI Design, Microwave Engineering, Optical Communication, Mobile Communication, Wireless Networks, Embedded Systems and CMOS Mixed-Signal VLSI.
The final-year project lets you apply what you have learned. Choose a project that produces a working prototype, measurable results or a simulation with real results. This gives you practical work to discuss in interviews.

3 Subjects That Make Your Foundation
These three subjects form the foundation for many advanced topics in electronics and telecommunication engineering.
Signals and Systems
You’ll learn key concepts such as convolution, Fourier transforms, Laplace transforms and sampling. They also appear in digital signal processing (DSP), communication systems, control systems, and image processing. Start by solving problems by hand, and then use Python or MATLAB to check your understanding.
Electromagnetic Field Theory
This subject connects vector calculus with the physics of electric and magnetic fields. The concepts can take time to understand, but they are useful in antenna design, microwave engineering, optical fibre communication, and high-speed circuit-board design.
Digital Communication
This subject covers modulation, noise, error probability, and information theory. These concepts explain how digital information travels through communication systems.
Skills to Build Beyond the Syllabus
The syllabus covers the basics, but most electronics and telecommunications engineering roles also need practical skills. These four skills are worth acquiring in college.
C and embedded C
Write code and run it on a microcontroller board to understand how hardware and software work together.
Python or MATLAB
Use these tools to analyse signals, create plots, and run basic simulations.
Verilog or VHDL
Learn digital design and practise implementing circuits on an FPGA board. These skills are useful for chip-design roles.
Circuit design tools
Use LTspice to simulate circuits and KiCad to design circuit boards. If your college provides access, explore industry-standard electronic design automation (EDA) tools for chip design.
The government’s Chips to Startup (C2S) programme provides chip-design tools to various academic institutions, and SCL Mohali fabricates chips designed through the programme. Ask your department whether your college participates. You can also check the official programme website for the list of institutions.
