How the radio works?

Have you ever wondered how the radio works, this ingenious invention has transpired. For years due to its usefulness AND versatility, in this article we will explain it to you. What is the mechanism that is used so that you can tune in to your favorite music and enjoy the content that travels miles away or even through the network.

How does the radio work?

Radio is a remote sound transmission that is carried out through electromagnetic waves which are capable of reaching various places quickly and simultaneously by means of a receiving device.

There are various ways of transmitting sound: by radio am means amplitude modulation, FM means frequency modulation, there is also short wave, transmission, via satellite, among others.

The main difference between amplitude modulation and frequency modulation Is that the first one has a lower sound quality But it can travel great distances because the antenna of its Transmitter Tower is very high and it is usually located in the outskirts of the city is therefore radio waves in this case travel through the earth’s surface.

On the other hand, FM offers excellent sound quality, but the coverage range is less. Compared to the amplitude modulated because the stations of this frequency are always located in high places to avoid the physical obstacles that the waves can encounter during their journey to the radio. These are easily recognizable metal towers why do they usually have special metal screen at the top.

The sounds or radio signals are born at various points such as a microphone, equipment, sharing a computer, telephone, etc. The truth is that these sounds are mixed in the radio studio by means of a console and, from there, they are sent through a cable to a equipment known as an audio processor, which is responsible for processing the entire wave and giving it the necessary touches to improve sound quality.

The link transmitter is connected through a cable and transports the sound to the place where the transmitting antennas of the station are located, in this way the link transmitter compacts the sound in some way and transfers it in a means of transport so that can travel.

Across the distance in what we call frequency. The transmitting power antennas are in charge of modulating or in some way repackaging the sound and transmitting it to the public.

The frequency with which said sound is packaged is what we tune into our radios and what allows us to listen to the music that we like so much or enjoy our favorite programming.

Thus, there is a frequency for each station which is specific and assigned by the Ministry of Communications of the country in which said radio operates. However, all broadcasting frequencies are organized and legislated under special agreements.

Now you know how it is possible that the sound emitted from a radio broadcast studio can be reproduced on your playback equipment. It is a fairly complex but at the same time ingenious technical process that has taken several decades to perfect and is expected to continue to improve in the future.

However, due to the technological advances that are currently being implemented, it is clear that there are already new modalities that have somehow managed to displace the conventional radio that we all know. Even so, having a mass communication medium like this is a privilege that we must always value and strive for.

The radio is a useful and efficient resource to be informed, communicated and entertained that you can also take with you everywhere. We invite you to read other articles that are published on our blog about the radio.
