Radio frequency (RF) refers to the rate of oscillation of electromagnetic radio waves in the range of 3 kHz to 300 GHz, as well as the alternating currents carrying the radio signals. This is the frequency band that is used for communications transmission and broadcasting. Although RF really s...
Radio frequency is measured in units calledhertz(Hz), which represent the number of cycles per second when a radio wave is transmitted. One hertz equals one cycle per second; radio waves range from thousands (kilohertz) to millions (megahertz) to billions (gigahertz) of cycles per second. In...

AM Versus FM Mode Of Modulation As mentioned earlier, AM involves the alteration of the amplitude of the carrier wave, whereas FM involves changes in the frequency of the carrier wave. Frequency Range The typical frequency range in which AM works is 535 to 1705 Kilohertz, whereas the frequency...
FM (also known as frequency modulation) works on a simple concept in order to generate a wide range of sounds spanning gritty basses, metallic percussion, distorted effects, and more. When it comes to signal processing,modulationsimply means changing certain properties of a periodic signal (like...
A frequency band is simply the range orintervalofradio frequenciesused to transmit a signal over a telecom network. All bands -- of which there are many -- are identified by their lower and upper limits. All these various frequency bands are part of the overall electromagnetic spectrum. The ...
FM doesn't offer any such metadata, just the frequency number. (Image credit: What Hi-Fi?) Which is better: FM radio or DAB radio? DAB and FM are two different formats: DAB is digital, while FM is analogue, but which sounds best depends entirely on the strength of the signal and ...
