The radio has evolved significantly since its invention, with improvements in technology leading to better sound quality and increased functionalities. Two such advancements are FM (Frequency Modulation) and DAB+ (Digital Audio Broadcasting) broadcasting, which have revolutionized the way we listen to the radio. In this article, we will discuss the basics of these broadcasting techniques and introduce the ALANO ALK101 module, a DIY kit that allows you to explore and understand these broadcasting techniques on a deeper level.
Understanding FM Broadcasting
FM broadcasting, invented in 1933 by American engineer Edwin Armstrong, uses frequency modulation to transmit high-fidelity sound over broadcast radio. This technology offers higher fidelity—more accurate reproduction of the original program sound—than other broadcasting techniques like AM broadcasting. It also has better rejection of static (RFI), making it less susceptible to common forms of interference. FM radio stations use the very high frequency range of radio frequencies, typically between 87.5 to 108.0 MHz, and the frequency of an FM broadcast station is usually a multiple of 100 kHz.
Introduction to DAB+ Broadcasting
DAB+ broadcasting is a digital radio standard primarily used in Europe that offers high-quality sound, improved reception, and more station choices than traditional FM radio. By transmitting digital data, DAB+ allows for the reception of additional information like song titles, music type, and news or traffic updates. It typically operates within the 174-240MHz frequency range and provides better sound quality than FM when reception is good, making it an excellent choice for music broadcasting.
