A brief History of Radio

Gagliemo Marconi demonstrating apparatus he used in his first long distance radio transmissions in the 1890s.

Hey everyone!

let’s talk about radio invention. Don’t forget we can do it.

Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form. https://www.youtube.com/watch?v=BJU2YjF8zz4

Around the start of the 20th century, the Slaby-Arco wireless system was developed by Adolf Slaby and Georg von Arco. In 1900, Reginald Fessenden made a weak transmission of voice over the airwaves. In 1901, Gagliemo Marconi conducted the first successful transatlantic experimental radio communications. 1896 Marconi develops a radio transmitter and goes into business. His ‘wireless telegraph’ used radio waves to carry messages in Morse Code.  He uses the radio transmitter to go into business (Marconi Wireless Telegraph Company). 1906 De Forest invents vacuum tube. The grid Audion was the first device to amplify, the strength of received radio signals. Made possible long-distance telephone service, radio broadcasting, television (De Forest Radio Telephone & Telegraph Company).

The two part of station are AM and FM.AM Amplitude modulation signal  that travel further suiting rural settings. Carries information in the height or amplitude of the radio wave. 33% of stations. And FM Frequency Modulation signal, which is wider, better fidelity, original sound cheaper licensing. Carries information in the frequency of the radio wave.  67% of all commercial stations, attract 75% of listeners.

in-conclusion, we now have an idea on radio invention. Don’t forget we can do it!!!
