it is range of frequency variation for which governor does not take any proportional corrective action.

In frequency modulation system, the maximum usable deviation be fixed +- 5 KHz and test deviation be kept 60% i.e. 3 KHz for wireless telephony systems used in military and other organisations. But wide band fm systems used in commercial broadcasts having frequency deviation +- 75 KHz.
All amplifier typically exhibit a band-pass frequency response. The cut off frequency in the low end is usually determined by the coupling band bypass capacitor .and the high frequency limit is typically determined by internal capacitances in the transistor itself.
A signal is said to be a band limited signal if all of it's frequency components are zero above a certain finite frequency. i.e it's power spectral density should be zero above the finite frequency.
The IBOC Broadcast System stands for the In-band on-channel system. In-band on-channel incorporates both digital and analog radio signals which transmit together on the same frequency.
This frequency range is used for A.M Radios specifically M.W(Medium Wave) Band. More information of MW band will be on http://en.wikipedia.org/wiki/Medium_wave

Broad band is a given range of frequencies, starting at a lower frequency through to an upper frequency, Base band is usually a specific frequency on which various modulation methods can be employed. But it too, can have a frequency range, or `band width' that considered part of the base band but yet called a single frequency based on the frequency's `center frequency'. A base band frequency for instance that's used in analog TV transmissions can range from 6 to 8 megahertz wide, on which the video, sound, color and other information is imposed. Broadband, usually used in computing terms, usually implies something like a DSL modem that can work from a few bits per second up to thousands of bits per second. It can either be wired or wireless, much the same as with a base band system.
It means to restrict the governing mode of the turbine when the frequency falls below 49.0 hz or rises above 50.5 hz with some presetting data band .
