Hence there are two types of radio broadcasting viz. AM and FM. The AM radio system uses maximum bandwidth of 10KHz while FM radio system uses maximum bandwidth of 200KHz. As a result AM carriers are spaced 10 KHz apart while FM carriers are spaced 200 KHz apart.
AM radio broadcasting system uses RF frequencies from 540 to 1600 KHz with IF of 455 KHz while FM radio broadcasting system uses RF frequencies from 88 to 108 MHz with IF of 10.7 MHz. Now-a-days radio sets are available in mobile, tablets, smartphones etc. Due to this, it has become more popular among people.
