What Is DAB Radio?
DAB (Digital Audio Broadcasting) radio is a digital radio technology that offers higher sound quality and more features compared to traditional AM/FM radio. It uses digital signals to broadcast audio content, which results in a clearer and more stable sound. DAB radio also allows for multiple channels to be broadcast on a single frequency, making it possible for listeners to access a wider range of stations.
DAB radio is widely used in many countries, including the UK, Australia, and parts of Europe. It is available on a variety of devices, including standalone DAB radios, car stereos, and smartphones. Some DAB radios also offer additional features, such as pause and rewind functionality, and the ability to display information about the current song or program.
What Is AM Radio?
AM (Amplitude Modulation) radio is a type of analog radio technology that uses amplitude modulation to broadcast audio signals. It is one of the oldest forms of radio broadcasting and is still widely used today. AM radio signals are broadcast on medium wave frequencies, which can travel long distances and are less affected by physical barriers.
However, AM radio signals are also prone to interference and can be affected by weather conditions, which can result in poor sound quality. Additionally, AM radio has limited bandwidth, which means that it can only broadcast a limited number of stations. Despite these limitations, AM radio remains a popular choice for many listeners, particularly for talk radio and news programs.
