Answer #1

Carson's rule is helpful in finding the bandwidth required for a carrier signal that is frequency modulated by a continous or broad spectrum of frequencies instead by single frequency.

According to Carson's Bandwidth rule,

Bandwidth required=2*(Peak frequency deviation+highest frequency in modulationg signal)

For narrow bandwidth FM, bandwidth=2*(highest frequency in modulating signal)

For wideband FM, bandwidth=2*(Peak frequency deviation+highest frequency in modulationg signal)
