d) Explain why a high frequency carrier signal is needed in a communication system.​

Respuesta :

Answer:

High frequency carrier signal has high power than low, so the information can be transmitted to a longer distance without distortion.

Explanation:

Instantaneous amplitude of the carrier signal is varied in proportion to the message signal. Since, frequency of the carrier signal is very high, the energy of the message signal improves and the information can be transmitted to a longer distance without distortion
