Answer to Question #268079 in Electric Circuits for Derek

Question

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?  

Answer 1

We know that

$∆f=9500Hz\\f_m=300Hz$

Maximum Band width

$B=2(∆f+f_m)$

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