Find out the voltage gain magnitude equation for the wide band-pass filter.

A. A<sub>Ft</sub>√ó( f/f<sub>L</sub>)/‚àö[(1+(f/f<sub>h</sub>)<sup>2</sup>]√ó[1+(f/f<sub>L</sub>)<sup>2</sup>].
B. A<sub>Ft</sub>/ ‚àö{[1+(f/f<sub>h</sub>)<sup>2</sup>]√ó[1+(f/f<sub>L</sub>)<sup>2</sup>]}
C. A<sub>Ft</sub>/ ‚àö{[1+(f/f<sub>h</sub>)<sup>2</sup>]/[1+(f/f<sub>L</sub>)<sup>2</sup>]}
D. [A<sub>Ft</sub>/(f/f<sub>L</sub>)]/ ‚àö{[1+(f/f<sub>h</sub>)<sup>2</sup>]/[1+(f/f<sub>L</sub>)<sup>2</sup>]}
Answer» B. A<sub>Ft</sub>/ ‚Äö√Ñ√∂‚àö‚Ć‚àö‚àÇ{[1+(f/f<sub>h</sub>)<sup>2</sup>]‚Äö√†√∂‚àö‚â•[1+(f/f<sub>L</sub>)<sup>2</sup>]}
