What is the modulation type that can be a frequency hopping of one carrier or multiple simultaneous carriers?

Question 1 of 27070

What is the modulation type that can be a frequency hopping of one carrier or multiple simultaneous carriers?

🔍 Key Concepts

• Spread spectrum techniques such as frequency hopping • Difference between single-carrier modulation (like SSB, FM) and multi-carrier or hopping methods • Meaning of FSK / OFSK (frequency-shift keying / orthogonal frequency-shift keying)

💭 Think About

• Which option refers to a technique where the signal energy is deliberately spread over a wider bandwidth than necessary? • Which of these can involve rapidly changing (hopping) the frequency of a carrier or using many narrow carriers at once? • Which of these is normally used as a basic voice modulation method on marine radios, and which are more associated with digital data and anti‑jamming techniques?

✅ Before You Answer

• Verify which choice is commonly associated with frequency hopping in communications theory • Check which modulations (SSB, FM, FSK/OFSk, spread spectrum) are typically narrowband single‑carrier methods • Confirm which option is defined as using multiple frequencies over a wide band either sequentially (hopping) or simultaneously
