1. The problem statement, all variables and given/known data http://www.wifstrand.se/albert/stuff/p13.3-6.png [Broken] 2. Relevant equations From circuit analysis I've found the network function to be H(ω) = -(10^(-4) +jωC1)/(1/R2 + jωC2) (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 C1 = 25 nF, but I can't find R2 and C2. In a solutions manual I read that k = 32 dB = 40 = R2/R1 from which I can find C2. I can tell the information is gathered from the Bode plot but I don't know how to arrive at this answer.
