Single-sideband modulation — (SSB) is a refinement of amplitude modulation that more efficiently uses electrical power and bandwidth. It is closely related to vestigial sideband modulation (VSB) (see below).Amplitude modulation produces a modulated output signal that has… … Wikipedia
Amplitude-companded single-sideband modulation — ACSSB (amplitude companded single sideband) is a narrowband modulation method using a single sideband with a pilot tone, allowing an expander in the receiver to restore the amplitude that was severely compressed by the transmitter. This mode… … Wikipedia
Radio — is the transmission of signals, by modulation of electromagnetic waves with frequencies below those of visible light.Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of… … Wikipedia
Radio receiver design — is a complex topic which can be broken down into a series of smaller topics. A radio communication system requires two tuned circuits each at the transmitter and receiver, all four tuned to the same frequency. [Cheney, M., Uth, R., Glenn, J.… … Wikipedia
Radio transmitter design — In plate modulation systems the voltage delivered to the stage is changed. As the power output available is a function of the supply voltage, the output power is modulated. This can be done using a transformer to alter the anode (plate) voltage.… … Wikipedia
Sideband — The power of an AM signal plotted against frequency. Key: fc is the carrier frequency, fm is the maximum modulation frequency In radio communications, a sideband is a band of frequencies higher than or lower than the carrier frequency, containing … Wikipedia
Radio Data System — The RDS Logo Radio Data System, or RDS, is a communications protocol standard for embedding small amounts of digital information in conventional FM radio broadcasts. RDS standardises several types of information transmitted, including time,… … Wikipedia
Shortwave radio — Shortwave can also refer to a shortwave trough meteorology. A solid state, analog shortwave receiver Shortwave radio refers to the upper MF (medium frequency) and all of the HF (high frequency) portion of the radio spectrum, between… … Wikipedia
Types of radio emissions — The International Telecommunication Union uses an internationally agreed system for classifying radio frequency signals. Each type of radio emission is classified according to its bandwidth, method of modulation, nature of the modulating signal,… … Wikipedia
Amateur radio history — Throughout the history of amateur radio, amateur radio enthusiasts have made significant contributions to science, engineering, industry, and social services. Research by amateur radio operators has founded new industries, built economies,… … Wikipedia
Citizens' band radio — Typical 1980s CB base station, used with outdoor antenna. This radio may also be used in an automobile, since it is powered by 13.8V DC. Shown with Astatic Power D 104 desk mic … Wikipedia
