What are the four 4 applications of angle modulation?

Angle modulation, including frequency modulation (FM) and phase modulation (PM), has a wide range of applications in telecommunications. Here are four common applications:

 1. Radio and television broadcasting: FM is widely used for radio broadcasting due to its superior noise resistance and high fidelity. FM signals can transmit stereo sound and other auxiliary information, and they are compatible with existing receivers. PM is also used in certain television broadcasting systems.

 2. Mobile communications: FM and PM are used in mobile communication systems to transmit voice and data over wireless networks. FM is used in some analog cellular systems, while PM is used in certain digital cellular systems.

 3. Satellite communication: FM and PM are used to transmit signals between satellites and ground stations. The wide bandwidth and high signal quality of angle-modulated signals make them well-suited for satellite communication.

 4. Data transmission: FM and PM can be used to transmit digital data over communication channels. In digital communication systems, PM is often used because it can transmit more data per unit of bandwidth than other modulation techniques.

Overall, angle modulation is a versatile and reliable technique for transmitting information over a communication channel, and it has many applications in modern telecommunications.
