Hi guys,
The question I need help with is
"Determine the maximum gain possible that meets the high-frequency roll-off specification of fH = 20 kHz."
http://i44.tinypic.com/ezlo2x.png
As you can see from my schematic & bode plot, I designed the roll-on to be at 100Hz and it rolls off at 815kHz.
How do I mathematically find the bandwidth or the cutoff frequency? I understand that to find the roll-on you simply do 1/(2piR2C1). I assume that once I find out how to find cutoff freq, I can design the roll-off at 20kHz and find the gain.
Thank you,
KC
