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.
cap F cap B cap W equals the fraction with numerator f sub cap H minus f sub cap L and denominator f sub c end-fraction cross 100 % f sub cap H : Upper frequency limit (often the -3 dB or -10 dB point). f sub cap L : Lower frequency limit. fractional bandwidth calculator
