GATE 2021 Electronics & Communications Engineering Syllabus (Released) – Get (ECE) PDF Here
GATE 2021 Syllabus of Electronics & Communications Engineering has been Released. Graduate Aptitude Test in Engineering (GATE 2021) is an examination that primarily tests the comprehensive understanding of the candidates in various undergraduate subjects in Engineering/Technology/Architecture and postgraduate level subjects in Science. Its Exam is Conducted by IIT Bombay.
The GATE 2021 score of a candidate reflects a relative performance level in a particular subject in the examination across financial assistance for several years.
The score is used for admissions to postgraduate programs (e.g., M.E./M.Tech/ Direct Ph.D.) in centrally funded Indian Institutes of higher education (i.e., Institutes which financial assistance by MHRD and other Government agencies).
