A modal realization has a block diagonal structure consisting of \(1\times 1\) and \(2\times 2\) blocks that contain real and complex eigenvalues. A PFE of the transfer function is used to obtain first and second-order factors in the transfer function model.3. While I know how to find the transfer function from the response graph, I don't know how to find it from Bode plot. What I know about the system: The system is a second order system. The system has no zeros. According to the Bode plot, I estimate that there is a double pole at w=2.5. therefore, I need to find Wn, zeta and K. This is the graph:A transfer function is a convenient way to represent a linear, time-invariant system in terms of its input-output relationship.

It is clear from the transfer function that there is a zero at s = 0 rad/sec and a pole at $$\frac{1}{R(C1+C2)} = \frac{1}{100k*2*(0.5*10^{-6})} = 10$$ rad/sec. Are these answers all correct, and are they complete? Have I missed something?Mar 19, 2023 · I think I'm really just confused about simplifying the transfer function. I understand now that the transfer function is just Vo/Vi = Zp/(R+Zp), where Zp is the total impedance of the two components in parallel. Maybe I am not calculating Zp correctly, I have Zp = Zl/(ZcZl+1). So substitution for Zp gives me Vo/Vin = Zl/(ZlZcR+R+L).
