CS601 - Data Communication Assignment No.2 Solution

Solution 

Question. 1

Given below is signal encoding of bit stream using B8ZS. You are required to give the missing bits in the given bit stream for this encoding in given table.

Solution

- 0 0 0 - + 0 + - 0 0 + 0 0

Question. 2

Consider a periodic signal which is decomposed into seven sine waves with frequencies 200, 100, 900, 500, 800, 700 and 400 Hz, what is the Bandwidth of this signal? Give your answer with complete calculations and proper unit in given table.

Solution:

Bandwidth of signal= highest frequency-lowest frequency

Bandwidth of signal=900-100

Bandwidth of signal=800

Calculation	Bandwidth	Unit
Bandwidth of signal=higest frequency-lowest frequency Bandwidth of signal=900-100                                 =800	800	Hz
