So an analog Radio works
Sounds are made up of invisible vibrations in the air called sound waves. The presenter speaks into the microphone, the sound waves electronically.
- These sound waves are now combined by the radio waves. This process is called Modulation. Radio waves are electromagnetic waves, which move much faster and further than sound waves.
- Due to very high Sendemäste the radio waves are broadcast. The range of a transmission tower can be as much as several hundred kilometers. So you can listen to, for example, the Radio-station "Radio Hamburg" is also 100 km far away.
- Since humans can't hear the radio waves, you will be received by Radio via an antenna and translated. While the recorded sound waves are again separated by the radio waves and reproduced via the loudspeakers.

- The digital technology of radio brings a number of advantages. The analog Signal can be interfered with by numerous influences, even through the rain. Also, the digital Signal is always disturbed, and yet the sound remains clear, since there are only zeros and ones. A Zero is also detected distorted as a Zero. In addition, other information, such as the artist of a song on the Radio.
