2. In _________________________, the amplitude of the carrier wave changes

AM radio transmission

S

In AM radio transmission, the amplitude of the carrier wave changes to carry the audio signal. This is achieved by varying the strength of the carrier wave in proportion to the amplitude of the audio signal. As a result, the peaks and troughs of the carrier wave are modulated to match the varying amplitude of the audio signal, allowing the signal to be transmitted over long distances and received by radio receivers.

3. ___________________systems use digital technology to make television interactive.

Video on demand

S

Video on demand systems use digital technology to make television interactive. With video on demand, viewers can choose and watch video content whenever they want, rather than being limited to scheduled programming. This technology allows users to pause, rewind, fast-forward, and even interact with the content through features like interactive menus and additional information. By providing a personalized and interactive viewing experience, video on demand systems enhance the traditional television experience and give viewers more control over their entertainment choices.

4. In ________________________, the frequency of the carrier wave changes.

FM broadcasting

S

FM broadcasting is a type of radio broadcasting where the frequency of the carrier wave changes. Unlike AM broadcasting, which varies the amplitude of the carrier wave, FM broadcasting modulates the frequency to transmit audio signals. This modulation technique allows for higher quality sound and less susceptibility to interference. FM broadcasting is commonly used for commercial radio stations and offers a wider range of frequencies, providing more channels for broadcasting.

5. _______________________ work differently than other music players. They have a solid-state memory that has no moveable parts.

Digital music players

S

Digital music players work differently than other music players because they have a solid-state memory that has no moveable parts. This means that instead of using a traditional spinning hard drive, digital music players use flash memory to store and play music. This makes them more durable and less prone to damage from physical shocks or drops. Additionally, solid-state memory allows for faster access to music files, resulting in quicker navigation and playback.
