FMkaistanleveydestä

FMkaistanleveydestä, also known as FM broadcasting bandwidth, refers to the range of frequencies allocated for FM radio broadcasting. FM radio operates in the frequency range of 87.5 MHz to 108 MHz in most countries, with each station typically allocated a bandwidth of 200 kHz. This bandwidth allows for the transmission of high-quality audio signals, which are less susceptible to interference and static compared to AM radio.

The FM broadcasting bandwidth is divided into channels, each with a center frequency that is a multiple of 100 kHz. For example, a station broadcasting at 90.9 MHz would be using the 90.9 MHz channel. The bandwidth allocated to each station is crucial for ensuring that adjacent stations do not interfere with each other, a phenomenon known as co-channel interference.

The use of FM broadcasting bandwidth is regulated by national and international bodies to ensure efficient use of the radio spectrum. In many countries, the allocation of FM broadcasting bandwidth is part of a broader spectrum management strategy that aims to balance the needs of different users, including television, mobile communications, and other services.

FM broadcasting bandwidth is a critical resource for radio broadcasters, as it enables them to deliver high-quality audio content to listeners. However, the increasing demand for radio spectrum, driven by the growth of mobile communications and other services, poses challenges for the sustainable use of FM broadcasting bandwidth. As a result, there is ongoing discussion and research into alternative technologies and spectrum management strategies to address these challenges.
