If we want to determine the bandwidth at a given frequency f, we should determine the 3dB fractional bandwidth.
according to the Shannon formula, we can calculate the bandwidth to be:
Bandwidth at f =3db_Bandwidth*f
on the other hand when plot the frequency vs received power to determine the 3dB_bandwidth, we have the bandwidth to be twice of the 3dB_bandwidth.
Can these two values be different?
if so what is the difference between the two approaches?
