Is there any actual loss due to FM transmission bottlenecks?

themctipers

Let's say theroretically you have a perfectly designed and operated radio station that outputs 50Kw and lets say you have the highest end FM radio and they both are PERFECTLY tuned into 108MHz, is there any audio loss?

Samsung 850 EVO 240 GB 

138 is a good number.

When there are no other Radiosignales Yes! But thats not the case. FM theoretically needs infinit bandwith the hole Radio - Spectrum. In practice we cut of the bandwith and dont care about the audio information loss. 

Did you mean:

"When there are no other radio signals, yes! But that's not the case. FM theoretically needs infinite bandwith for the whole radio spectrum but in practice we cut off the bandwith and don't care about the audio loss."

Is there audio loss if you have ALL the frequencies untouched and at 0? This is from 1hz-ooTHz.

If we have all the frequencies than there is perfect transmission possible !

 

PS: Sorry for my english.

It's ok! I am bad at english too! I'm just good at making it look good.

There are a lot losses FM broadcasts are limited to 15khz in most cases. 19khz is the highest possible frequency.

 

No discrete stereo and probably some more issues.

AM is usually pretty expensive though.

You would need about 5 MHz of bandwidth (+/- 2.5 MHz) for full stereo audio transmission. Digital signals (HD radio) piggyback the audio signal so it is less restricted by the frequency and more restricted by the speed at which the encoder and decoder work.

 

Assuming that the transmitter and receiver are perfect and there is no atmospheric loss with infinite bandwidth then you will have not signal loss.
