# GATE 2017 Electronics and Communication Engineering (EC) Syllabus

Last Updated - October 23, 2016

Graduate Aptitude Test in Engineering, GATE is conducted every year for admission into post-graduate programmes in various institutes across India. The exam is conducted every year by one of the IITs or IISc. IIT Roorkee is the organizing institute for GATE Exam this year. Various Public Sector Undertakings also use the GATE Score for the purpose of shortlisting candidates for various job openings.
