Electronics and Communications Engineering (ECE) is one of the largest and fastest growing fields of engineering. The present Global Technology revolution is changing the world and is offering challenging opportunities to specifically Engineers. ECE is a subfield of core Electrical Engineering. Graduate level.

The basic aim is to produce products that are smaller, smarter and multi-functional. The ability of electronic devices to act as switches makes digital information processing possible. Electronics & communication Engineering offers scope in the field of research, mobile communication, Microwave communication, robotics, defense, radio communication, TV broadcasting, telegraphy & telephony, VLSI design, DSP, nuclear science, wireless communication and biotechnology

This field is closely aligned with Computer Science and Engineering (CSE) and the advances in CSE play a significant role in the advancement of ECE. This is why a degree in ECE is always in high demand.
