This post gives latest GATE Syllabus for Instrumentation Engineering. It will be updated if any changes are announced by the GATE organizing institute. This GATE syllabus is a part of GATE Exam info and Preparation Guide. I would also recommend you to refer A set of ‘Must Read’ articles for M.Tech aspirants which I wrote over a year answering questions of M.Tech aspirants.

have a good day.. this is very nice. it is very useful of all engineers

john

Sir,I have completed my B.Tech in E.C.E branch and i want to join M.Tech in INSTRUMENTATION engineering in IIT’s.i’ve heard that changing of branches is not possible in IIT’s or can we change our branch like that.

dev

hello sir, i have completed B.E in electronics & instrumentation. can i apply for gate exam .what will be the syllabus.
