What frequencies do FM stations occupy?

FM stations occupy frequencies in the range of 88 to 108 MHz. This band is designated for commercial and non-commercial FM radio broadcasting in many countries. The choice of 88 to 108 MHz is significant because it has been allocated specifically for FM radio, allowing for high-fidelity sound transmission, which is a hallmark of FM broadcasting.

The lower limit of 88 MHz ensures that there is a clear cutoff from the AM broadcasting band, while the upper limit of 108 MHz provides a balance so that there is sufficient space for various broadcasting stations without causing interference among adjacent channels. This 20 MHz segment is particularly suited for FM broadcasting, enabling high-quality audio transmission and reception.

Other options do not represent the actual frequency range used for FM radio. Frequencies beyond or below this range either lead to other types of transmissions or fall outside the designated FM band. Understanding this frequency allocation is essential for anyone working in the field of radio transmission and reception, making it critical for technicians to be familiar with these details.
