Q

What is Frequency?

A

Frequency describes the number of waves that pass a fixed place in a given amount of time.
Frequency is Denoted by: Hz

Q

What is Fading of a Frequency?

A

Fading occurs when both signals are received both by Ground wave and Sky wave paths.
The signals combine with each other to disrupt and fade away.
Fading an occur due to Weather conditions, Objects and Time of Day.

Q

What is Attenuation?

A

The gradual declination of Electromagnetic due to Weather, Obstacles like Lead that absorb Electromagnetic Waves and even the Atmosphere doing different times of the day.

Q

What is AM? Its Advantages.

A

AM is where the Amplitude is varied along with the Carieer Wave.

The Advantage of AM is that it forms SSB and DSB which can give more options in the amount of information passed, Range, Spectrum and Power required.

Q

What is FM? Its Advantages.

A

FM is where the Frequency is varied along with the Carrier frequency but the Amplitude remains the same.

The Advantage of FM is it has an improved signal to noise
