FMradiotaajuudet

FMradiotaajuudet refers to the radio frequency band used for Frequency Modulation (FM) broadcasting. This band is typically allocated within the Very High Frequency (VHF) spectrum, specifically between 87.5 and 108 megahertz (MHz) in most parts of the world, although some regions may have slight variations. FM radio transmission works by varying the frequency of the carrier wave in accordance with the audio signal being transmitted. This modulation technique offers a higher fidelity sound reproduction compared to Amplitude Modulation (AM) radio, making it ideal for music broadcasting.

The FMradiotaajuudet band allows for the transmission of a relatively wide range of audio frequencies, contributing to its clear sound quality. Interference is generally less of an issue with FM than with AM, especially over shorter distances, as it is less susceptible to atmospheric disturbances and electrical noise. However, FM signals have a more limited range than AM signals, as they tend to travel in straight lines and can be obstructed by geographical features like hills and buildings. This necessitates a denser network of transmitters for widespread coverage. The allocation of specific frequencies within the FMradiotaajuudet band is managed by national regulatory bodies to prevent interference between different radio stations.
