In __, the amplitude of the carrier wave is changed to transmit information; the frequency is not changed.
The type of modulation that describes this is called amplitude modulation (AM). In AM, the amplitude, or height, of the carrier wave is modulated or varied to represent the information being transmitted. The varying amplitude carries the audio or data signal, while the frequency of the carrier wave remains constant.
To get more information about amplitude modulation and how it works, you can search for "amplitude modulation" or "AM modulation" on reliable sources or academic publications. Additionally, you can refer to textbooks or online tutorials on telecommunications or radio communication principles.
In __, the frequency of the carrier wave is changed.
The type of modulation that describes this is called frequency modulation (FM). In FM, the frequency of the carrier wave is modulated or varied to represent the information being transmitted. The changes in frequency carry the audio or data signal, while the amplitude of the carrier wave remains constant.
To understand the concept of frequency modulation and how it works, you can search for "frequency modulation" or "FM modulation" on reliable sources or academic publications. Textbooks or online resources on telecommunications or radio communication principles would also provide detailed explanations.
__ phones and __ phones use radio waves to transmit signals.
Mobile phones and cordless phones use radio waves to transmit signals. Radio waves are a form of electromagnetic radiation that can carry information wirelessly over long distances. Mobile phones use cellular networks that consist of base stations, while cordless phones typically operate within a limited range from their base station.
To gather more information about mobile phones and cordless phones, you can search for these topics on reliable sources, technology websites, or telecommunication equipment manufacturer websites.
__ use electromagnetic signals from a base station.
Wireless devices like Wi-Fi routers, laptops, or smartphones use electromagnetic signals from a base station to establish wireless connections. These signals are typically in the form of radio waves or microwaves. The base station, such as a Wi-Fi router or a cellular tower, transmits the signals, which are then received by the wireless devices, allowing them to communicate and exchange data.
To explore further information on wireless communication and base stations, you can search for "wireless communication," "base station," or "wireless networking" on reliable sources, technology websites, or telecommunication industry publications.
Communication __ enable radio signals to be sent from one part of Earth to another.
Communication satellites enable radio signals to be sent from one part of the Earth to another. These satellites are positioned in geostationary orbits above the Earth and act as relay stations for transmitting signals. They receive signals from ground-based stations and retransmit them to other parts of the Earth, allowing long-distance communication and global coverage.
To delve deeper into communication satellites and their functionality, you can search for "communication satellites" or "geostationary satellites" on reliable sources, space agency websites, or telecommunication engineering references.
The __ consists of satellites, ground-based stations, and portable units with receivers used to help locate objects on Earth.
The system being referred to here is the Global Positioning System (GPS). GPS is a navigation and positioning system that utilizes a constellation of satellites, ground-based control stations, and portable units equipped with GPS receivers. The satellites orbit the Earth and constantly broadcast signals containing precise timing and positioning information. GPS receivers on the ground or in mobile devices receive these signals and use the information to calculate precise locations, allowing users to determine their position anywhere on Earth.
To gain a deeper understanding of the Global Positioning System (GPS), you can search for "GPS" or "Global Positioning System" on reliable sources, GPS manufacturer websites, or navigation technology publications. Additionally, consulting textbooks or academic resources on satellite navigation systems can provide extensive explanations.
