🔍 Key Concepts

• Amplitude modulation (AM) vs frequency modulation (FM) • What sidebands and carrier are in an AM signal • The meaning of suppressed carrier and why it might be useful

💭 Think About

• In AM, what are the three main components of the transmitted signal when the carrier is NOT suppressed? • If a device is called a "balanced" modulator, what might it be balancing or canceling out in the output signal? • Which type of AM signal is often used to save power and reduce wasted bandwidth by removing the carrier but keeping the information?

✅ Before You Answer

• Identify which options mention sidebands and which mention carrier behavior. • Decide which modulation type (FM or AM) normally uses a balanced modulator in communications theory. • Confirm which choice specifically describes double sideband with suppressed carrier (DSB-SC), a key term you should recognize.
