Radio noise, the Glossary
In radio reception, radio noise (commonly referred to as radio static) is unwanted random radio frequency electrical signals, fluctuating voltages, always present in a radio receiver in addition to the desired radio signal.[1]

Antenna (radio)
In radio engineering, an antenna (American English) or aerial (British English) is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver.
See Radio noise and Antenna (radio)
Atmospheric noise
Atmospheric noise is radio noise, or "static", caused by natural atmospheric processes, primarily lightning discharges in thunderstorms. Radio noise and atmospheric noise are noise (electronics).
See Radio noise and Atmospheric noise
Communications satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth.
See Radio noise and Communications satellite
Computer
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation).
Cosmic noise
Cosmic noise, also known as galactic radio noise, is a physical phenomenon derived from outside of the Earth's atmosphere.
See Radio noise and Cosmic noise
Cryogenics
In physics, cryogenics is the production and behaviour of materials at very low temperatures.
See Radio noise and Cryogenics
Electric motor
An electric motor is an electrical machine that converts electrical energy into mechanical energy.
See Radio noise and Electric motor
Electromagnetic compatibility
Anechoic RF chamber used for EMC testing (radiated emissions and immunity). The furniture has to be made of wood or plastic, not metal. Log-periodic antenna measurement for outdoors Electromagnetic compatibility (EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage to operational equipment.
See Radio noise and Electromagnetic compatibility
Electromagnetic interference
Electromagnetic interference (EMI), also called radio-frequency interference (RFI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction.
See Radio noise and Electromagnetic interference
Electromagnetic radiation
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy.

Frequency
Frequency (symbol f), most often measured in hertz (symbol: Hz), is the number of occurrences of a repeating event per unit of time.
IEEE Transactions on Electromagnetic Compatibility
IEEE Transactions on Electromagnetic Compatibility is a peer-reviewed scientific journal published bimonthly by the IEEE Electromagnetic Compatibility Society.
See Radio noise and IEEE Transactions on Electromagnetic Compatibility
Ignition system
Ignition systems are used by heat engines to initiate combustion by igniting the fuel-air mixture.

International Telecommunication Union
The International Telecommunication Union (ITU)French: Union Internationale des Télécommunications is a specialized agency of the United Nations responsible for many matters related to information and communication technologies.

Johnson–Nyquist noise
Johnson–Nyquist noise (thermal noise, Johnson noise, or Nyquist noise) is the electronic noise generated by the thermal agitation of the charge carriers (usually the electrons) inside an electrical conductor at equilibrium, which happens regardless of any applied voltage. Radio noise and Johnson–Nyquist noise are noise (electronics).

Lightning
Lightning is a natural phenomenon formed by electrostatic discharges through the atmosphere between two electrically charged regions, either both in the atmosphere or one in the atmosphere and one on the ground, temporarily neutralizing these in a near-instantaneous release of an average of between 200 megajoules and 7 gigajoules of energy, depending on the type.
Longwave
In radio, longwave, long wave or long-wave, and commonly abbreviated LW, refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band.
Medium wave
Medium wave (MW) is a part of the medium frequency (MF) radio band used mainly for AM radio broadcasting.
See Radio noise and Medium wave
Noise
Noise is sound, chiefly unwanted, unintentional, or harmful sound considered unpleasant, loud, or disruptive to mental or hearing faculties.
Passband
A passband is the range of frequencies or wavelengths that can pass through a filter.
Radio
Radio is the technology of communicating using radio waves.
Radio frequency
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around to around.
See Radio noise and Radio frequency
Radio receiver
In radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form.
See Radio noise and Radio receiver
Radio telescope
A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky.

RF front end
In a radio receiver circuit, the RF front end, short for radio frequency front end, is a generic term for all the circuitry between a receiver's antenna input up to and including the mixer stage.
See Radio noise and RF front end
Shot noise
Shot noise or Poisson noise is a type of noise which can be modeled by a Poisson process. Radio noise and Shot noise are noise (electronics).
See Radio noise and Shot noise
Signal-to-noise ratio
Signal-to-noise ratio (SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. Radio noise and signal-to-noise ratio are noise (electronics).
See Radio noise and Signal-to-noise ratio
Switch
In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another.
Ultra high frequency
Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimeter).
See Radio noise and Ultra high frequency
Very high frequency
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter.
