Question #268079

What is the maximum bandwidth of an FM signal with a deviation of 9500 Hz and a maximum modulating signal of 300Hz as determined by Carson’s rule?

Expert's answer

We know that

$∆f=9500Hz\\f_m=300Hz$

Maximum Band width

$B=2(∆f+f_m)$

B=2(9500+300)=2\times9800=19600Hz \\B=19.6KHz
