C-DOT Placement Paper Pattern 10 June 2007

 

I gave my test on 10-06-07. I was not selected but I hope this paper will help you in some way.

 

Selection Process consists of Written Test (objective) followed by an interview.

 

The paper is different for both computer science and electronics and communication. Both have their respective technical questions. Written Test for ECE students. This year the paper consisted of 100 questions. It had questions on following topics:

 

Communication engineering

 

1. 10-18 ques.

2. PCM, AM, FSK, DPSK… NUMERICALS & Objective q

3. Autocorrelaton

4. OFC (5-10q)

 

Digital Electronics

 

1. AROUND 10 q

2. How many half adder and or gates required for 4 bit adder.

3. Boolean equations

4. Totem pole output

 

Analog electronics

 

1. 20-30 question

2. Transistors, electron hole concentration… etc

3. Numerical based on base current n all

 

Microwave Engineering

 

1. 10 q

2. one was like wave guide acts as? A high pass filter(ans)

3. Range of radar one numerical.

 

One or two questions from networking and one was from C it was based on binary and linear search. One or two questions were also based upon logical ability like set theory (simple one).

 

I remember this much only. I would suggest the toppers from the ECE branch from their respective colleges And students preparing for GATE must apply even if they have the JOB, you people will definitely clear the exam.

PROFILE

 

The Centre for Development of Telematics (C-DOT) is the Telecom Technology development centre of the Government of India. It was established in August 1984 as an autonomous body. It was vested with full authority and total flexibility to develop state-of-the-art telecommunication technology to meet the needs of the Indian telecommunication network. The key objective was to build a centre for excellence in the area of telecom technology.

 

While the initial mandate of C-DOT in 1984 was to design and develop digital exchanges and facilitate their large scale manufacture by the Indian Industry, the development of transmission equipment was also added to its scope of work in 1989.
