The frequency and phase remainthe same.In FM, a radio wave known as the carrier or carrier wave is modulated in frequency bythe signal that is to be transmitted. The amplitude and phase remain the same.Pros andconsAM has poorer sound quality compared with FM, but is cheaper and can be transmittedover long HYPERLINK http//www.diffen.com/difference/AM_vs_FM distances. It has a lowerbandwidth so it can have more stations available in any frequency range.FM is less prone tointerference than AM. However, FM signals are impacted by physical barriers. FM has bettersound quality due to higher bandwidth.Frequency RangeAM radio ranges from 535 to 1705 KHz(OR) Up to 1200 bits per second.FM radio ranges in a higher spectrum from 88 to 108 MHz.(OR) 1200 to 2400 bits per second.Bandwidth RequirementsTwice the highest modulatingfrequency. In AM radio broadcasting, the modulating signal has bandwidth of 15kHz, and hencethe bandwidth of an amplitude-modulated signal is 30kHz.Twice the sum of the modulatingsignal frequency and the frequency deviation.
