Hello, I am approximating the bandwidth of an FM signal using Carson's rule.
I am finding that it is consistently less than the method of visually summing the frequency amounts between each significant sideband as viewed on a spectrum analyser.
Is there a particular reason for this ? Is it because Carson's rule is simply an approximation method and not that accurate ?
Thanks kindly for any ideas.
