## The Attempt at a Solution

Hello all,

I've derived a transfer function, [tex]T(s) = \frac{\frac{-R_{2}}{R_{1}}}{1 + \frac{1}{sCR_{1}}}[/tex], but I can't seem to derive the corner frequency.

I am suppose to derive the corner frequency and show that it is indeed, [tex]\omega_{o} = \frac{1}{CR_{1}}[/tex]

The only way I know how to obtain the corner frequency was how I obtained it using a low pass filter. I set the magnitude of my transfer function at the corner frequency equal to my DC gain divided by √(2).

But in a high pass filter my DC gain is 0. (This is what you would expect, it allows high frequencies to pass and attenuates low frequencies, and at DC [tex]\omega = 0[/tex])

So how do I solve it? Can someone nudge me in the right direction?

Thanks again!
