Can you obtain a transfer function in frequency domain with a bode plot form given by this function: $$ S=k1 \sqrt{1+\frac{k2}{f}} $$ I did not managed it because actually in the lowest part of frequencies decreases with 10dB/dec. So is not a simple pole (20dB/dec) and zero function. Maybe it is possible to obtain such function by adding many low pass filters. Any idea?

  • $\begingroup$ @Ch.SivaRamKishore The purpouse is to obtain a transfer function with a form similar to the plot of S(f). Off course, the S is dependent by the frequency but not expressed in term of s. $\endgroup$ – Ba5o Dec 27 '18 at 16:49
