E CIL 2012 solved questions with answers ECIL EC branch questions with answers

Hello Friends. I am Sabhyata.I have written ECIL GET 2012  paper for EC. Paper was not really tough, if you know the fundaments of all important subjects of EC branch.
The paper was for 150 marks.Toatal 50 questions were there , each carrying 3 marks. Negative marking of 1 marks for each wrong answer.
The subjects you need to prepare are:
1. RADAR
2. Microwave & waveguide
3. Digital ckt
4.Network analysis
5. Control system- 2 or 3 questions
6.Electronic device and circuits-  basic

So  remember only few questions,  Iam posting here:-

1.From RADAR, PRF frequency given,we have to find maximum usable range .
2. From RADAR,time taken is given we have to find Range of RADAR.
