Which of the following statements describes the carrier?

Question 1 of 27070

Which of the following statements describes the carrier?

🔍 Key Concepts

• Carrier wave definition in radio communications • Difference between carrier, modulating (information) signal, and sidebands • How modulation (AM/FM) uses the carrier to convey information

💭 Think About

• Ask yourself: What is a carrier by itself, before any information is added? Is it already complex, or is it a simple RF signal? • Which statement describes a basic property of a carrier wave, not something that is always true only when modulation is present? • Which options confuse the carrier itself with the effects of modulation, like sidebands or multiple frequencies?

✅ Before You Answer

• Identify which option clearly states that the carrier is an RF signal with no extra conditions. • Check which options talk about sidebands or multiple frequencies—are those properties of the carrier alone or of the modulated signal? • Make sure the choice you pick would still be true if no intelligence (information) were being transmitted on the carrier.

Question 1 of 27070

Which of the following statements describes the carrier?

The carrier consists of at least 3 separate but closely spaced frequencies.

The carrier is used to modulate the information signal.

There are always sidebands on either side of the carrier.

The carrier is a Radio Frequency (RF) signal that is modulated to carry intelligence .
