Carrier waves are used for communicating signals over long distance, because
- A carrier waves can be generated very easily.
- B low frequencies can not be easily modulated by the carrier waves.
- C low frequencies can be transmitted over long distances.
- D carrier waves generated at higher frequencies can be transmitted over long distances.
Answer & Solution
Correct Answer
(D) carrier waves generated at higher frequencies can be transmitted over long distances.
Step-by-step Solution
Detailed explanation
Low frequency signals have very low energy, hence, they can not transmitted over long distance without modulation. In modulation, characteristics of carrier wave is varies according to the amplitude of low frequency (messages signal). Carrier waves are high frequency signal…
