How FM Radio Works: A History and Exploration of Frequency Modulation

[@WECB640]

This is beautifully presented. It is easy for the layman to understand, yet enjoyable for the radio engineer at the same time. Take a bow, you earned it. 73

Thank you so much!

I’ve been trying to get over the broad-strokes understanding of FM stereo radio hump for like 5 years and this video finally did it. I was just looking for something to watch while I made coffee. You’re making the internet a better place, thanks!

[@BroadcastBlueprint]

I’m glad it helped! Thank you for watching

The best description of AM and FM I've seen. 100 years of radio in 34 minutes: quite a feat. I had the privilege of meeting Tom Lewis when his book was released and the film was in production. Thanks for all your work. K4XBC

[@BroadcastBlueprint]

That’s high praise! Thank you so much!

[@basshorseman998]

With 35+ years in radio (also amateur), this was a great overview with some detail that I was very impressed with...well done...Thanks

[@maksymmoroz]

Thank you for your work, man. Very clear. I was surprised that the video has less than 100k views

[@cateclism316]

I understand AM and FM a little better because I worked with analog music synthesizers in college. I also remember FM's ascendance in the 1970s, and how crisp and clear it was compared to AM stations.

Thank you for naming this video and taking the time to put so much detail.

[@jaredbater6229]

What an absolutely fantastic video. Amazing explanations!

[@BroadcastBlueprint]

Glad you liked it!

[@FrostyDog9186]

An amazingly good video!

[@ChrisGoosman]

Fantastic video! Pre- and De- emphasis, as well as the curves used in various noise reductions schemes, is also somewhat analogous to the RIAA curve used when cutting and then playing back vinyl. I've been involved in disc cutting in my lifetime, and like FM, it's magic and a wonder that it works as well as it does, ha!

[@BroadcastBlueprint]

When I want the challenge of not knowing why something works when it clearly shouldn’t, I go straight to audio and RF electronics!

[@christopherjones2283]

bravo! well done professor

[@redthepost]

Thank you for helping me resurrect my interest in broadcasting technology. Fun stuff.

[@turbo2ltr]

two thumbs up. great video.

[@sophiapriest]

I love this video! It was so informational, and I loved the metaphors and examples you provided as well. I'm slowly learning about this type of stuff to someday work in the radio industry, and I this also explained a lot about things I've noticed but didn't understand much about while using my SDR! Thanks for this video, and I can't wait to see what you'll upload next!

[@BroadcastBlueprint]

Glad it helped you learn something new! That's my goal when making these videos.

[@michaelcox436]

Excellent, thank you

[@TVJAY]

This is an amazing video. Thank you for making it. I will share this with a lot of people.

Explain HD AM and FM. Most broadcasters have given up on HD AM

[@Flagrazi]

Best explanation I've seen. Tks. 73

[@barrygeary1890]

Has pre emphasis on fm anything to do with reducing high frequencys?

[@BroadcastBlueprint]

Sort of… since there’s more noise at higher audio frequencies in the demodulated signal, pre-emphasis helps reduce that high frequency noise while trying to keep the modulating signal intact.

Such great and high quality content. Hopefully you'll get more subs and views soon :-).
