Identification of three poles

Hi everyone!

I have a question regarding system identification of a system with 3

I have a feel for the three time constants (1/pi) that I am trying to
identify. They are approximately 0.5 sec, 3 sec and 20 sec

I am trying to generate a Psuedo Random Binary Sequence (PRBS) that
contains the range of frequencies that the input signal should have in
order to capture the dynamics due to the three poles.

(1) Could you give me an idea as to what the frequency range should

(2) I am currently generating the PRBS signal using a combination of
rand() and randn(). However, this is an iterative process where I
have to keep checking to see if the required frequency range is
present. Could some one tell me how I could generate the PRBS signal
with the specific frequency range using Matlab without the process
being iterative? Any code/pointers would be greatly appreciated.

Thank you.
