Hello, I’m Avinto, and in this section, we’ll explore Telecommunication—the technology that allows us to communicate over long distances. We’ll explain Amplitude Modulation (AM) and Frequency Modulation (FM), which are used to encode information in radio waves. We’ll also discuss the basic components of a communication system, including transmitters and receivers, and how radio and TV signals are transmitted and received. Finally, you’ll learn about designing simple telecommunication devices like radios and transmitters.
