- Modulation
- Demodulation
- Transduction
- Amplification
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.
