What's the difference between FM and AM radio stations?!

Question: What's the difference between FM and AM radio stations!?
AM stands for “amplitude modulation” – a type of signal!. With AM, the amplitude of the combined audio frequency and radio frequency waves varies to match the audio signal!. AM radio can develop problems with interference!. This makes it hard to hear the radio show!. Interference can be caused by many sources!. For example, sparks discharge when a car is started, in electric motors in all sorts of electrical appliances, and even lightning!. All of these things can produce interference to AM radio!. As you can see, there is a lot of background noise that changes the amplitude of the radio wave signal!. This creates the random crackling noises call static!.

FM stands for “frequency modulation”- a type of radio transmission, the frequency of the combined waves change to reproduce the audio signal!. For example, higher frequency is associated with the peak amplitude in the audio wave!. FM waves do not have a problem with interference because the noise background does not modify the radio wave frequency!. In addition FM waves give better sound reproduction!.

To the lay person the difference is quality!. FM sounds better, but AM signals travel farther!. FM (Frequency Modulation) are radio waves that are shorter!. This characteristic mean the FM signal will propagate more freely into underpasses and garages!. AM (Amplitude Modulation) are radio waves that are large and can travel for many miles!.Www@Enter-QA@Com

FM = Frequency Modulation
AM = Amplitude Modulation

It has to do with how the stations are tuned!. FM is based on the frequency of radio waves (how often the occur) and AM is based on amplitude (how "big" they are)!. That's putting it in very simple terms

also, FM has stereo capabilities, while AM does not!. The gal who said AM is gospel hasn't got a clue!. AM is really country, religion, and high school football : -)Www@Enter-QA@Com

the frequency in which they broadcast their signals!.


Frequency modulation versus amplitude modulation!. Or do you mean, talk radio versus music radio!?Www@Enter-QA@Com

i have no idea but i listen to fmWww@Enter-QA@Com

am is gospelWww@Enter-QA@Com
