GATE 2019 Syllabus for Electronics and Communications
About GATE 2019 – To offer admission into M.Tech/M.Sc in engineering/ technology/ architecture and P.hD. GATE 2019, In relevant branches of science, Graduate Aptitude Test in Engineering (GATE) is a national level examination, and it is conducted Mock Tests have been released. It has to be mentioned that, GATE 2019 is managed by the IIT.
Of the GATE 2019 subjects, two categories have been divided into each. Overall, in regards to the core subjects, the corresponding sections (of the syllabus given below) of the question paper will contain 90% of their questions and the remaining 10% on Special Topics.
Like transmitter, receiver, integrated circuits (IC), Electronics & Communication Engineering deals with the electronic devices, circuits, communication equipment. It also deals with basic electronics, analogue and digital transmission & reception of data, voice and video (Example AM, FM, DTH), microprocessors, satellite communication, microwave engineering, antennae and wave progression. On the basic concepts and theories that will equip them in their professional work involving analysis, systems implementation, operation, production, and maintenance of the various applications in the field of Electronics and Communications Engineering, It aims to deepen the knowledge and skills of the students.
