How modulation helps in carrying message over a large distance?

Question

Accepted Answer

Modulation helps in carrying messages over large distances by allowing the signal to travel efficiently without losing strength or clarity.

Modulation allows for the message signal to be combined with a carrier signal, which helps in long-distance transmission.
It helps in reducing interference and noise during transmission.
Different types of modulation techniques like amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM) are used for efficient communication over long distances.
For example, in AM modulation, the amplitude of the carrier signal is varied in proportion to that of the message signal, allowing for the message to be transmitted over long distances.
