If u see the frequency response of an amplifier, initially the gain increases, then remains constant for some time and then decreases. If we draw a line 3dB below the contant frequency region we get two point , one at the increasing gain region and the other at the decreasing gain region. The frequency range between these two points respectively called as fl and fh is called midband frequency range.
What else can I help you with?
Is the midband gain and the center of frequency the same?
The mid-band gain is the gain of a range of frequencies that lie beween the lower frequncy and the upper frequency. The center frequnecy is the geometric mean between the lower frequncy and the Upper frequnecy. In resonant circuits it is the frequnecy where the gain is at maximum.
Definition of half-power frequency?
The frequency on an amplifier response curve which is greater than the frequency for peak response and at which the output voltage is 1/√2 (that is, 0.707) of its midband or other reference value.
What do the letters GB stand for?

What animal has the best eye site?
It's either the Great horned owl or and eagle. Eagles are the best at distance. They can see 8x further than we can. The owl can see things from 50 yards and see in the dark. The eyes of the Mantis Shrimp is also very good. The midband region of the mantis shrimps eye is made up of six rows of specialized ommatidia. Four rows carry 16 differing sorts of photoreceptor pigments, 12 for colour sensitivity, others for colour filtering. The mantis shrimp has such good eyes it can perceive both polarized light, and hyperspectral colour vision . Their eyes (both mounted on mobile stalks and constantly moving about independently of each other) are similarly variably coloured, and are considered to be the most complex eyes in the animal kingdom.They permit both serial and parallel analysis of visual stimuli. It just depends on the environment.
