Frequency range of FM Broadcast is
(A) 80 MHz – 110 MHz
(B) 88 MHz – 110 MHz
(C) 80 MHz – 108 MHz
(D) 88 MHz – 108 MHz
Correct Ans: (D)
Explanation:
FM (Frequency Modulation) radio operates within the 88 MHz – 108 MHz frequency range. This spectrum ensures high-quality audio transmission with minimal interference. Therefore, FM radio remains a popular choice for music, news, and talk shows.
Moreover, FM broadcasting offers better sound clarity compared to AM radio, which suffers from static and signal disruptions. The higher frequency range allows FM signals to transmit with less noise, making it ideal for entertainment and communication. Consequently, FM radio is widely used for public broadcasting and commercial stations.
In addition, different countries regulate FM frequency allocations. While 88 MHz – 108 MHz is the standard range in most regions, some countries may have slight variations. As a result, broadcasters must comply with national regulations to avoid signal overlap.
Furthermore, FM signals travel in a line-of-sight pattern, meaning they work best in urban areas with fewer obstructions. However, signal reach is limited compared to AM, which can travel long distances. Therefore, FM stations use multiple transmitters or relay stations to expand coverage.
To conclude, the FM broadcast frequency range of 88 MHz – 108 MHz provides superior audio quality and reliable transmission. Its widespread use in radio broadcasting ensures diverse content for audiences worldwide. Therefore, FM radio remains an essential part of modern communication.
