What do Tianzhu am and fm mean?

Teana AM and FM are two common communication modes in radio stations. AM, namely amplitude modulation, is a traditional broadcasting method, which is often used in medium and short wave broadcasting. Its advantage is that the signal propagation distance is long and it is suitable for large-scale reception. FM (frequency modulation) is a relatively novel broadcasting method, which belongs to high-definition broadcasting. It can play higher quality music and information, but the signal propagation distance is shorter than AM.

AM and FM are two ways for radio stations to spread signals, and there are also great differences between them. First of all, AM has stronger sound penetration and is suitable for long-distance transmission, but its sound quality is poor and it is easily disturbed. FM sound is not as penetrating as AM, but its sound quality is clearer and less susceptible to interference, so it is suitable for local transmission. In addition, FM can be equipped with noise suppression technology, which can avoid signal distortion caused by environmental noise, thus improving the broadcast signal quality.

Although Teana AM and FM are different in the traditional broadcasting mode, their applications in the broadcasting field have their own characteristics. AM is suitable for some specific services, such as military communication, live broadcast, weather forecast, etc. For mass broadcasting, FM is widely used in the world, which can provide higher quality music and information. Nowadays, AM and FM are not only broadcasting tools, but also provide convenience for music, news, sports and other fields, and become an indispensable part of our daily life.
