Hello guys
Welcome to vishltech ......
As you all know, I am doing my engineering from electronics and communication branch, so for engineering students to join PSU's job or to get admission in m.tech from IIT's and NIT's GATE examination is a very good path . Now we have come to know that the gate exam is very useful but we do not know what is coming in this exam, so today we will go through this blog. In this blog, today we will discuss the Gate Examination 2020 Electronics and Communication Engineering syllabus.
Let me give you an overview of the GATE syllabus, there is a paper numbering 100 of which 70% are core subjects of electronics and communication engineering which you study in the 2nd and 3rd year. And out of the remaining 30%, 15% is Engineering Mathematics and 15% is General Aptitude. so lets get started ..
