GATE 2020 is one of the biggest national level organized by IITs every year. It is only the entrance test that have a total of 24 papers for various subjects. The syllabus for all those papers will vary. It is important for the GATE 2020 applicants to be aware of the **GATE syllabus for ECE** (Electronics and Communication Engineering) to start their exam preparation. Now, we shall know about the ECE paper syllabus along with the exam pattern here.

## GATE ECE Syllabus 2020

As every other GATE 2020 paper, ECE paper also comes with a total of 65 questions. Among them 55 questions will be from the subjects of the ECE and the remaining 10 from the general aptitude. The GATE 2002 syllabus for ECE will have all the topics and the sub-topics from the subject that candidates have to prepare for the exam.

The GATE 2020 syllabus for ECE PDF will have a total of 8 sections covered in it and they are, Engineering Mathematics; Networks, Signals and Systems; Electronic Devices; Analog Circuits; Digital Circuits; Control Systems; Communications and Electromagnetics. All these are the topics that are covered in the ECE course at 3^{rd} and 6^{th} semester. So, applicants can easily prepare them as they are already aware of the subjects. The syllabus PDF is available in the official website and candidates can directly download it. Or otherwise, go through the below table to have a glance at complete syllabus.
