Who Invented FM Radio
The radio is one of the most significant inventions in history. We wouldn't have been able to broadcast vital information during wartime or alleviate a nation's depression without radio waves. Mobile phones, microwaves, and even walkie-talkies have all been invented due to them.

The question is, where and when did it all begin? Learn more about the history of FM radio in this article!

Why was FM radio created?

FM radio was invented because it was supposed to focus on sound quality instead of signal strength. The transmission of voices and music is possible through signal strength, but static noise would also come through. FM radios were able to reduce or eliminate it by focusing on improving audio signals.

The first FM broadcasts took place in 1937, and by 1988 over 1,000 stations were broadcasting the format across the world.

Who is the founder of FM radio?

In 1933, Edwin Howard Armstrong invented FM radio. He was an American electrical engineer who developed many technologies still used in radios and televisions today, including frequency modulation (FM), superheterodyne receivers, and wideband transmission. Without his efforts, our radios would be a lot less clear.

It took a few years for the technology to be developed and for stations to start broadcasting in FM. There are several reasons why it became so popular:

●        its sound quality was superior to AM;

●        it could carry more information (stereo sound);

●        it was less susceptible to interference than AM.

FM radio is still widely used today. Nowadays there are even digital FM broadcasts that can carry data as well as audio signals. This makes FM a versatile tool for both broadcasting and transmitting information. For example, many cars come with built-in FM transmitters that allow you to play music from your phone or other devices through the car's stereo system.

FM is also used for emergency broadcasts and public information services. So, next time you're tuning in to your favorite station, remember that FM radio has come a long way since it was first patented over 80 years ago!

How does FM radio work?

FM radio operates at higher frequencies than AM. It can be 100 MHz to 300 MHz, but usually, the range is between 88-108 MHz for commercial FM broadcasts and between 50-75 MHz or 65-68 MHz for amateur use. Because they don't travel as far at night and are less susceptible to electromagnetic interference, these waves also have different characteristics.

FM receivers tune in to a particular frequency, or channel, and demodulate the signal to reproduce the sound. The receiver is usually designed to suppress the image frequency and reject it so that only the desired channel can be heard.

The invention of FM radio has had a profound impact on the way we communicate and consume media. It isn't just a way to get access to news, sports events, and music. It's also an important part of our culture. If you enjoy listening to FM radio as much as we do, let us know in the comments what your favorite stations are so we can keep each other company!
