yes!, but the AM carriers aren't supposed to reach frequencies of FM carriers. AM freq range for eg from 700KHz to 1500KHz where as FM ranges 86MHz to 109MHz approx. This standard is for radio broadcast, however the AM modulation freq is always lesser than FM.safwatonline said:in AM waves the information is in the envelope so at a unit time the amount of information is the same whatever the carrier frequency
The carrier frequencies have nothing to do with the amount of information sent\received per given time. They help in carrying after all. It is the information signal which we send has the information. Need more info to be sent short in time?,use more bandwidth. Thats what they do.safwatonline said:it seems confusing to me,
lets say we have a PSK signal if i used the same signal with a carrier fc=1MHz this doesn't give any lower information than using the same signal with a carrier with fc=2MHz
as the information is in the signal and has nothing to do with the carrier
if u do not modulate the baseband signal then just imagine ur antenna size. U will not be able to have a mobile phone in ur pocket.rag_perfect said:If high frequeny attenuates more then that will be a disadvantage of modulation.but nowhere i have seen this fact??? plz help....
and frnds can anybody explain:
Is it true that Baseband can not travel to longer distance by itself??
