2. Component
 Broadband
 Baseband
 Transmission Impairment
 Noise
 Attenuation
 Distortion

3. Broadband
 It is a high-data-rate connection to
the Internet. Broadband is the
transmission of wide bandwidth data
over a high speed internet
connection
 - frequency division multiplication
 - it’s send frequency value using
optical fiver, wireless, cable, satellite

4. Baseband
 It’s a digital technology for data
transmission. Baseband Transmission
is a signaling technology that sends
digital signals over a single frequency
as discrete electrical pulses.
 - it’s send the binary value directly a
pulse of different voltage level
 - it’s an one way signal transfer
 EX - audio signal output of a
microphone

5. Transmission Impairment
 It means that signals that are transmitted at the beginning of the medium are
not the same as the signals that are received at the end of the medium that
is what is sent is not what is received
 - It’s an transmission traffic
Impairment cause
Attenuation Distortion Noise

6. Attenuation
 Attenuation means loss of energy that is the weaker signal. when a signal transmitted
through a medium it loses its energy, so that it can overcome by the resistance of the
medium
 - Amplifiers are used to amplify the signals to compensate for this loss.

7. Distortion
 If a signal changes its form or shape, it is referred to as distortion. Signals
made up of different frequencies are composite signals. Distortion occurs in
these composite signals.
 - different components have different delay in arriving at the final destination ,
signals have different phases at the receiver than they did at the source

8. Noise
 Noise is unwanted electrical or electromagnetic energy that degrades the
quality of signals and data. Noise occurs in digital and analog systems, and
can affect files and communications of all types, including text, programs,
images, audio etc.
