Fractional Bandwidth Calculator -

Note: For narrowband signals (FBW < 10%), the arithmetic and geometric means are nearly identical. For wideband signals, the difference becomes significant. A high-quality fractional bandwidth calculator will often allow you to select which definition of center frequency to use, or it will calculate the center frequency automatically based on the input cutoffs.

To use a fractional bandwidth calculator, you need to know three primary variables: fHf sub cap H : The upper cutoff frequency (Highest frequency). fLf sub cap L : The lower cutoff frequency (Lowest frequency). : The center frequency (usually the arithmetic mean of fHf sub cap H fLf sub cap L Fractional Bandwidth - an overview | ScienceDirect Topics fractional bandwidth calculator
