1. ## CS601 Assignment No. 2 Close Date is 15th December 2014

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.

Signal encoding Using B8ZS
Bit stream
?000??0??00?00

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.

Calculation Bandwidth Unit

2. LECTURE #16
Example 5.1
Using B8ZS, encode the bit stream 10000000000100. Assume that the polarity of the first 1 is positive.
Answer: One Zero Zero Zero Zero Zero Zero Zero Zero Zero Zero One Zero Zero

3. Q#1
Bit stream
10000000000100
Q#2

Calculation Bandwidth Unit
band=high(frequencies)-low(frequencies) 800 HZ
here h(f)=900
l(f)=100
band=900-100
band=800
this is true assignment

4. SOLUTION:

Bandwidth of Signal= Highest Frequency – Lowest Frequency
Bandwidth of Signal = 900 – 100
Bandwidth of Signal = 800

Calculation
Bandwidth
Unit
Bandwidth= Highest Frequency – Lowest Frequency
Bandwidth= 900-100=800
800
Hz
