🔍 Key Concepts

• Radio carrier signal and what it is used for • How voice or data (intelligence) gets sent over radio waves • Difference between modulation and simply changing frequency or encoding 1s and 0s

💭 Think About

• Ask yourself: what is the basic radio wave doing BEFORE anything is added to it, and what has to happen so that it can carry useful information like voice or data? • Which choice talks about the process of adding information to an existing radio wave, rather than changing where it is on the dial or how digital bits are represented? • Which options describe related but different processes (like frequency selection or digital encoding) instead of the core idea of modulation?

✅ Before You Answer

• Identify which option clearly involves adding information (intelligence) to a radio signal, not just changing its frequency or format. • Check that the correct option would apply to AM, FM, and digital radio methods, not just one specific technique. • Eliminate any choices that only describe frequency changing or digital bit coding without explicitly referring to adding information to a carrier.
