Question

Q.6) Which of the following is not a cause of signal impairment? *
O Attenuation
O Bandwidth
O Distortion
O Noise​

Answer 1

Answer:

Explanation:

The quality of the received signal may be impaired by many causes, such as noise, equipment distortions and/or mismatching, spectrum truncation, interference, propagation delay, and echo.

Answer 2

Bandwidth

There are three causes in signal impairment:

• Noise
• Distortion
• Attenuation

Noise:

Noise is a key cause of transmission distortion. Because any undesired signal is added to the broadcast signal, causing the resulting transmitted signal to be modified. It is difficult to remove the unwanted noise signal at the receiver end.

Distortion:

This type of distortion is most common in composite signals. A composite signal contains many frequency components, each of which has a temporal limitation, resulting in a full signal.

Attenuation:

Signal intensity is often reduced with attenuation, making the received signal difficult to receive at the receiver end.
