**GATE EC Syllabus 2017:** The Graduate Aptitude Test in Engineering (GATE) is an All-India Examination conducted by the seven Indian Institutes of Technology. As the GATE 2017 Exam date is approaching, it is time for the candidates to start preparing and secure admissions for various postgraduate programs in centrally funded Indian institutions. This year GATE examination will be organised by Indian Institute of Technology Roorkee. The details shall be posted on their official website i.e www.gate.iitr.ernet.in

Electronics and Communication Engineering involves the transmission of information across channels like coax cable or optical fiber. It also deals with designing equipments such as routers, switches, fiber optics and electronic switching systems. In a nutshell, this branch of engineering deals with electronic devices and software interfaces. There is a lot of scope in the realm of electronic communications engineering such as communications engineering, electronic engineering, electronic communications technician etc.

Before heading to the GATE EC syllabus and exam pattern, have a look at the eligibility criteria and important dates for GATE 2017.

**GATE EC Exam Pattern 2017**

Before heading to the GATE EC Syllabus, we should have a look at the exam structure and pattern. The exam pattern for computer science paper of GATE 2017 is same as that of previous year’s. There will be a total of 65 questions carrying 100 marks. The question wise break up is as follows:

Section | Question no. | No. of Questions |

General Aptitude | 1-10 | 10 |

Technical + Engineering Mathematics | 1-55 | 55 |
