(1) No supplementary answer-book will be given to any candidate. Hence the candidates should write the answer precisely in the Main answer-book only.
(2) All the parts of one question should be answered at one place in the answer-book. One complete question should not be answered at different places in the answer-book.
Turn over
A tlempt any five questions.
All questions carry equal marks.

and clean diagram.
2. (a) What are the transmission impairment factors?
Give the effect of noise on a digital signal.
(b) What is the difference between connectionless communication and connection-oriented communication.
3. (a) Explain in terms of data link control and physical
layer concepts how error and flow control are accomplished in synchronous time division multiplexing.
(b) Consider a transmission system using frequency division multiplexing. What cost factors are involved in adding one more pair of stations to the
system?
4. (a) Briefly explain AM, FM and PM and differentiate
between them.
