google: see Harris' shock and vibration handbook 1.19
The effective bandwidth of a specified transmission system is the bandwidth of an ideal system which (1) has uniform transmission in its passband equal to the maximum transmission of the specified system and (2) transmits the same power as the specified system when the two systems are receiving equal input signals having a uniform distribution of energy at all frequencies.
