So I did the first part, and got the gain as 11.
I also did part c, and got approximately 80khz,
but I'm not sure what to do for b).
I know that at the 3db frequency, the voltage is at 1/20.5 of it's amplitude.
So can I just use the equation f=(slew rate)/(2pi*A), and set A to 1V/20.5, and solve for f? In which case f=112.5khz
If not, what should I do?
