What is the process of modulating radio waves with electrical signals called?

Modulation
Demodulation
Transduction
Amplification

What are the two main types of modulation used in radio broadcasting?

Amplitude modulation (AM) and frequency modulation (FM)
Phase modulation (PM) and single-sideband modulation (SSB)
Pulse modulation (PM) and code modulation (CM)
Delta modulation (DM) and adaptive delta modulation (ADM)

What is the difference between AM and FM?

AM varies the amplitude of the radio waves, while FM varies the frequency.
AM varies the frequency of the radio waves, while FM varies the amplitude.
AM uses a single sideband, while FM uses both sidebands.
AM is more susceptible to noise than FM.

What are the advantages of AM over FM?

AM is less susceptible to noise.
AM is more efficient in terms of bandwidth usage.
AM is easier to implement and maintain.
AM is more compatible with older radio receivers.

What are the advantages of FM over AM?

FM is less susceptible to noise.
FM is more efficient in terms of bandwidth usage.
FM provides higher fidelity audio quality.
FM is less prone to interference from other radio stations.
