Q1
Why is received signal not as same as transmitted signal? Explain
in
brief.
ANSWER
- Analog signal consist
of varying a voltage with time to represent an information steam. If the
transmission media were perfectly, the receiver could receive exactly the same
signal that
Q2
What is communication channel? Explain with an example.
Answer
- Communication channel means a medium through which electrical signals can be
transmitted. A communication channel (or simply channel), refers either to a
physical transmission medium
Q3
What is carrier signal and a modulating signal? What are the uses
of
modulation?
Answer
-Modulation is the
process of varying one of characteristics (either amplitude or frequency or
phase) of a high-frequency periodic waveform, called the carrier signal, with a
modulating
Q4 What is Guided Transmission Media? List different types of
guided media.
Answer –
Transmission media is the physical path
between the transmitter and receiver. Physical media used for the
QNO5 State and explain Nyquist theorem with mathematical
representation..
Answer - The Nyquist theorem states that
“a signal must be sampled at least twice as fast as the bandwidth of the signal
to accurately reconstruct the waveform” In other words, the sampling frequency
should be
Answer
- Congestion control is
concerned with controlling traffic entry into a
network, so as to avoid congestive collapse by attempting to avoid
oversubscription of any of the processing or link
