Modulation Techniques | MCQs

Explanation

FM is not easily affected by amplitude variations caused by thunderstorms, making it more resistant to noise.

In contrast, Amplitude Modulation (AM) is highly susceptible to static and noise from electrical storms.

Explanation

The process used to convert digital signals into analog signals for transmission over communication channels is called modulation.

Modulation involves altering a carrier signal (which is analog) to encode the digital information,

Allowing it to be transmitted over mediums that typically carry analog signals, such as radio waves or telephone lines.
