What do you mean by DC component?
If a signal includes a component of zero frequency, that component is called DC
(Direct Current) component or constant component.
With no DC component, a signal has an average amplitude of zero. With a DC
component, a signal has nonzero average amplitude.

cs601 todays paper :)
Mcq's from the past papers..
except the one.. 
what is the bandwidth of telephone signals
3300
3000
3100
3200

Q-The freq is 5hz find the period. [2marks]
Q-what do u mean by zero frequency?how it affects the signal? [2 marks]
Q-which layer of the OSI controls the data rate and how it works? [3marks]
Q-Discuss the following interface standard (digram) jo mujhe nzr hi nhi ai :( [3 marks]
Q-What are the possible ways through which a signal containing DC component can send to receiver over transmission medium? [5marks]
Q-
a) What is the function of a modulator? What is the function of a demodulator? 
b) Explain the asymmetry of 56K modems
[5 marks]

Question No. 17: Give the names of any two devices that can be used for connecting among following situations:
1. LAN to LAN
2. LAN to WAN
3. MAN to WAN
Question No. 18: Phase Modulation is one of the methods used for :
1. Analog to Digital Conversion
2. Analog o Analog Conversion
3. Digital to Analog Conversion
Question No. 19: What will be the frequency of a signal completing 10 cycle in one second?
Question No. 20: If 64 bits are sent over transmission medium in one second, what will be the bit rate and bit interval?
Question No. 21: How does DTE and DCE works together for end to end communication?
Question No. 22: Using HDB3 scheme, encode the signal “1100001011”
Question No. 23: Give advantages and disadvantages of Asynchronous and Synchronous transmission. Compare the both strategies.

paper should be based on 100% mcqs!

all the MCQ's were 4om the past papers bt Q's were a little bit logical some of the Q's which i remember r

1.a sine wave has a frequency of 5HZ .what is its period,

2.how signals are controlled by

frequecy 
phase
amplitude

3. why we require plus code modulation of data when converting audio signal from analog-to-digital?

4.which function of the session layer provide communication in half and full duplix?

5.why do we group bits into longer groups to send from one device to another?
