Hi
Let's talk about the radio
Let's go back in the time:
1886
many research groups were looking for how to communicate wirelessly telegraphically
Although the fact of the invention of the radio to Guglielmo Marconi is merited, although the idea was in several countries simultaneously, Marconi was the only one who could integrate the existing knowledge related to sending and receiving into a single team of electromagnetic waves discovered by Hertz, Tesla, Branly, Lodge or Popov
Before the radio existed people were informed by letters or other writings. In addition, by means of the telegraph.
A telegraph is a machine used to transmit information encoded by electrical signals
the remote transmission of a sound through electromagnetic waves that are able to reach thousands of people quickly and simultaneously through a receiving device There are several ways to transmit radio: AM (Modulated amplitude) and FM (Modulated Frequency), shortwave, satellite, etc. The differences between AM and FM are mainly: The AM has low sound quality, but has the advantage that it can travel long distances
The FM has excellent sound quality and has a lower coverage than AM; FM stations are always located in high places because they need to avoid obstacles so that their waves can reach our radios
And colombia also has his history
