fm radio

is fm radio transmission analog or digital or both.
thanks
 

fm radio

FM transmission is analog. The quality is due to a better noise immunity of FM over AM.

But you can modulate digital signals and send it over FM like you can send digital data over analog telephone line.
 

Re: fm radio

fm is analog transmission......its clearer than am only bcos of the power spectral density being larger....the noise being spread in all the β+1 side bands on both sides....it can be digitised but i dont know if its actually done....also bcos the power wasted in the carrier is much less compared to am.....

FM RADIO is analog transmission.
 

Re: fm radio

if it is only analog then how could mobiles can receive fm radios.
thanks

I think mobile phone FM is a completely parallel electronics than GSM.
 

fm radio

An FM tuner and demodulator chip will be added to mobile phone to receive FM radio.
Such as TEA5761 of philips.
 

Re: fm radio

FM is analog, but in FSK (FSK is digital) , it has similarities to FM.
the difference in FSK: it onty uses 3 sets of frequency to be translated as rest, mark or space frequency. these frequencies represents the digital information signal as a 0 or 1 (in space and mark frequencies) and rest frequency represents the "off" state of the transmission (just to difference with the space frequency which represents 0).

Many analog methods, (may be all ones) can be implemented by digital techniques.
 

Re: fm radio

FM is a pure analog transmission.

Ofcourse there are digital modulation schems based on FM.
 

Re: fm radio

im fm radio we receivr the analog signal...than digital processing is done on the signal in digital circuits.......than tha output is again in analog.....sidra_maheen84@yahoo.com
