The main difference between AM and FM radio waves is that AM waves are amplitude modulated while FM waves are frequency modulated. AM waves are older and have a larger range, while FM waves have a smaller range but provide better sound quality. Back when people still used radios (instead of...
FM(FrequencyModulation)即调频。习惯上用FM来指一般的调频广播(76-108MHz,在中国为87-108MHz、日本为76-90MHz),事实上FM也是一种调制方式,即使在短波范围内的27-30MHz之间,做为业余电台、太空、人造卫星通讯应用的波段,也有采用调频(FM)方式的。FMradio即为调频收音机。 扩展资料 振幅调制分类: 1、双边带调幅 ...

AM radio broadcasts also require less complex equipment to receive and decode, increasing the ease with which a radio receiver can detect an AM signal. The primary advantage of FM is that it has a higher signal-to-noise ratio; therefore, FM is less susceptible to radio-frequency interference...
