AM vs FM

Today we will talk about two modulation methods in a radio field: Amplitude modulation (AM), and Frequency Modulation (FM): How they work, their differences and their applications.

No ads, no commercials just the learning videos, you are contributing a lot to my career grow, I love you Sunny!

[mcjumper]

The most simple and clear explanation on internet. You are a gifted teacher. Majority on here it's just garble..garble...garble only they understand. New subscriber.

[m.a.i]

Mr Sunny, you are got full respect. you make it easy on the eye!

[pavankumarenugula]

Sir your explanation is very well please make a video on delta modulation and differential pulse code modulation.

[gishilgeorge]

Thank you for making this video. It's so helpful.

[swagatnanda]

Sir absolutely helpful video
But also add phase modulation and also the mathematical theory aslo

[jfarr]

This is a great video. Well done. Learned lots.

Thank you Sunny for your excellent lectures!! In your previous lesson, you said carrier waves travel further than signals because they have higher frequency . Does it mean higher frequency waves have larger area coverage? IF SO, but in this lesson you said AM covers larger area because of its lower frequency! Do you mean, in general, carrier waves used in AM have a lower range than carrier waves used in FM? Thank you

Thanks Sunny. It's a wonderful lecture.

[Anonymous-edid]

Thanks Sunny. Very vivid. However, I'm a bit curious, if FM is immune to static, then why using AM sometimes? When will AM be used? And why？

[justquran]

Thanks sir! Very informative videos. I am from Pakistan

[methos]

Thanks for the video. Why is the frequency not affected? I can't find any resources that connect this topic to basic wave interference in physics.

[mcie]

thank you so much, what a great video!!!

[sure]

2:51 most of News radios are AM 原来是这样。我在aged

[fikret]

That is nicely video thank you so much

[ritchienavarro]

I still listen to am radio mostly for live sporting events.

[technicaltransistor]

hi sir, which tool you use to make these video

[salamatpanjaitan]

sir, why FM affected by physical barrier

[jancenj]

On FM, if the frequency is changing depending on the data signal, how can a radio receiver tune to that carrier frequency? Does frequency modulation actually change the carrier frequency?

[LiaLiana]

2:44 when we talk about data transmission, when we mean that we have a high bandwidth, then we have a high frequency range and thus the data can be transmitted over a longer distance, as far as I know. But here it says that AM frequency range is lower and that's why it can cover larger areas, and that would contradict what I said before. What am I missing? >.<
