BPUT DCT questions

I am the student of B.Tech 6th Semester of Biju Patnaik University of Technology and I have completed my preparation but I have some doubt in Digital Communication Technology subject so I need the previous year question paper of it can you please provide me this?

Hello sir, Im student of Biju Patnaik University of Technology looking for Digital Communication Techniques questions. Is there any one can provide me Biju Patnaik University of Technology Digital Communication Techniques question paper?

[pawan]

The Biju Patnaik University of Technology is provides Digital Communication Techniques question paper.

The Biju Patnaik University of Technology, Orissa, is lead with its head-quarters in Rourkela came into being in November 2002.

The main objective of instituting the University was to ensure a high quality of students coming out of the technical colleges through a common curriculum and uniform evaluation.

Biju Patnaik University of Technology Digital Communication Techniques question paper:


DIGITAL COMMUNICATION TECHNIQUE

Full marks:-70
Q.1 contains 20 marks and
Q.2- Q.8 contains 10 marks each (out of which 5 has to be done)
1.
(a) What is the need of signalling in a PCM system?
(b) State the properties of MSK modulation.
(c) What is the need of an anti aliasing filter?
(d) If the data transmission rate is R of a communication system, how much band width is required if you use BPSK modulation?
(e) What is white noise? Where is it encountered?
(f) Why pulse shaping is done? Is it a base band or pass band operation?
(g) What is the advantages of channel coding?
(h) Bring out 2 differences between thermal noise and quantization noise.

Quantization noise
(i) This is introduced in the transmitter and is carried along to the receiver output
(ii) Nq=S^2 /12

(i) The information is a speech wave form with maximum frequency content of 3.5 kHz. The quantization error is not exceeded +-1% of the peak to peak analogue signal. What is the sampling rate,minimum number of bits per sample and the minimum transmission rate?

(j) Can signal-to-noise ratio and channel bandwidth of a bandlimited, Gaussian channel be traded keeping channel capacity at optimum level?support your answer with suitable example.
4. Explain Shanons theorem and capacity of a Gaussian channel theorem.
