The syllabus is the very important part of the examination because it plays an important role in the examination.

## GATE Electronics and Communications Engineering  Syllabus (EC)

### ADMISSION OPEN 2019

Electronic engineering  is an electrical engineering discipline which utilizes nonlinear and active electrical components (such as semiconductor devices, especially transistors, diodes and integrated circuits) to design electronic circuits, devices, VLSI devices and their systems. The discipline typically also designs passive electrical components, usually based on printed circuit boards.

## GATE 2019 – Cut Off

GATE Cut off is the minimum marks to be eligible for admission to IITs and IISc. This is a factor deciding that either candidates is qualified in the exam or not. GATE 2019 cut off marks varies stream-wise and category-wise. The cut-off marks are less for reserved category candidates as compared to the unreserved category candidates.
