[Answer] Radio noise crossword clue

• Radio noise In radio reception, radio noise is unwanted random electrical signals, fluctuating voltages, always present in a radio receiver in addition to the desired radio signal. Radio noise is a combination of natural electromagnetic atmospheric noise ("spherics", static) created by electrical processes in the atmosphere like lightning, manmade radio frequency interference (RFI) from other electrical devices picked up by the receiver's antenna, and thermal noisepresent in the receiver input circuits, caused by the random therm…, also known as , is a signal or process with a frequency spectrum that falls off steadily into the higher frequencies, with a pink spectrum. It occurs in almost all electronic devices and results from a variety of effects.A or sferic (sometimes also spelled "spheric") is a broadband electromagnetic impulse that occurs as a result of discharges. Sferics may propagate from their lightning source without major attenuation in the Earth–ionosphere waveguide , and can be received thousands of kilometres from their source.In the United States, the 1982 Public Law 97-259 allowed the Federal Communications Commission (FCC) to regulate the susceptibility of consumer electronic equipment.Potential sources of RFI and EMI include: various types of transmitters, doorbell transformers, toaster ovens, electric blankets, ultrasonic pest control devices, electric bug zappers, heating pads, and touch controlled lamps. Multiple CRTcomputer monitors or televisions sitting too close to one another can som… is caused by natural atmospheric processes, primarily lightning discharges in thunderstorms. It is mainly caused by cloud-to-ground flashes as the current is much stronger than that of cloud-to-cloud flashes. On a worldwide scale, … and galactic is that originates outside the atmosphere. It can be detected and heard in .
