SpletShortwave radio is a frequency that operates somewhere between the FM and AM bands on your standard radio set. Shortwave can travel exceptionally long distances, which makes it an excellent option for anyone hoping to reach a wide audience. In Canada, the US, and Europe, local FM/AM broadcasting is freely available. 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 20 kHz to around 300 GHz. This is roughly between the upper limit of audio frequencies and the lower limit of infrared … Prikaži več Electric currents that oscillate at radio frequencies (RF currents) have special properties not shared by direct current or lower audio frequency alternating current, such as the 50 or 60 Hz current used in electrical power distribution Prikaži več Communications Radio frequencies are used in communication devices such as transmitters, receivers, computers, televisions, and mobile phones, to name a few. Radio frequencies are also applied in carrier current systems … Prikaži več • Amplitude modulation (AM) • Bandwidth (signal processing) • Electromagnetic interference • Electromagnetic radiation • Electromagnetic spectrum Prikaži več The radio spectrum of frequencies is divided into bands with conventional names designated by the International Telecommunication Union (ITU): Frequency range Wavelength range ITU designation IEEE bands Full name Abbreviation Below … Prikaži več Test apparatus for radio frequencies can include standard instruments at the lower end of the range, but at higher frequencies, the test equipment becomes more specialized.
