GATE Syllabus for ECE- Electronics and Communication Engineering

GATE 2023 is conducted by the IIT Kanpur. Recently It Released the GATE 2023 Exam dates which fall as 4th February, 5th February, 11th February, and 12th February in 29 disciplines across India. After 2015, 6 years later IIT Kanpur is organizing the GATE 2023 Exam again now.

GATE Electronics and Communication Engineering?
Electronics and Communication Engineering (ECE) is a branch of Engineering that deals with the design and application of circuits, devices, and systems that use electrical energy to control or transmit information. This includes the study of semiconductor devices, integrated circuits, antennas, communication systems, etc.

The basic aim of this branch is to help students understand the working principle of various electronic devices and develop their skills in designing and manufacturing them. ECE engineers are employed in a wide range of industries such as telecommunications, electronics, and aerospace engineering.

The gate syllabus for electronics and communication engineering specifies the topics that a student must know in order to qualify for the graduate Aptitude Test in Engineering.

The test is conducted by seven IITs and is used as the entrance examination for admission into Post-graduate programs in engineering and science streams, Management Programs, and Government Jobs in PSUs.
