2. Relevant equations

From circuit analysis I've found the network function to be

H(ω) = -(10^(-4) +jωC_{1})/(1/R_{2}+ jωC_{2})

(could be wrong)

3. The attempt at a solution

I don't know how to determine the network function from the Bode plot but my attempt is

H(ω) = (1 + jω/4000)/(1 + jω/400)

If I equate the first H(ω) with the second H(ω) from which I can get C_{1}= 25 nF, but I can't find R_{2}and C_{2}. In a solutions manual I read that k = 32 dB = 40 = R_{2}/R_{1}from which I can find C_{2}. I can tell the information is gathered from the Bode plot but I don't know how to arrive at this answer.
