FMtaajuuksiin

FMtaajuuksiin refers to the frequency bands used for Frequency Modulation (FM) radio broadcasting. In most parts of the world, FM radio operates within the VHF (Very High Frequency) spectrum. Specifically, the most common FM band is between 88 and 108 megahertz (MHz). This band is allocated internationally for FM broadcasting purposes.

The choice of this frequency range for FM radio offers several advantages. It allows for relatively wide channels, typically around 200 kilohertz (kHz) wide, which enables high-fidelity audio transmission. Signals in the FM band are less susceptible to atmospheric interference compared to lower frequency bands, leading to clearer sound quality. Furthermore, FM signals can travel longer distances than AM (Amplitude Modulation) signals, although their propagation is generally limited to line-of-sight, meaning they are affected by terrain and obstacles.

Within the 88-108 MHz range, different countries may have specific allocations or sub-bands. For instance, in Europe and many other regions, the standard FM band is 87.5 to 108.0 MHz. In North America, the band typically ranges from 88.1 to 107.9 MHz, with channels spaced at 200 kHz intervals. The allocation of these frequencies is managed by international bodies like the International Telecommunication Union (ITU) and national regulatory authorities. The term FMtaajuuksiin simply refers to these designated radio frequencies utilized for FM transmission.
