I need to manually create a second order digital filter for a set of data. I have carried out FFT on the data to identify the 4 sin waves the data is made up of and have identified the highest frequency sin wave as the one I wish to filter out....

## How To Find Zeta And Wn In Matlab

Its two arguments are the damping ratio (Zeta) and natural frequency (Wn) [these may be vectors if you want to look at a range of acceptable values]. In our problem, we need an overshoot less than 5% (which means a damping ratio Zeta of greater than 0.7) and a rise time of 1 second (which means a natural frequency Wn greater than 1.8). Enter in the Matlab command window:

- I want to design a second order reference model for an adaptive control system with a specific settling time and over shoot.
- The code that you posted generates a 57th (!!!!) order filter to perform the operation that you want to do. The freqz command does indeed show that this filter is valid, but attempting to implement such a high order filter directly without first converting it to 2nd order sections using tf2soswill undoubtedly result in serious numerical errors.

- order pole or zero make asymptotes, peaks and slopes n times higher than shown. For example, a double (i.e., repeated) pole has high frequency asymptote at -40 dB/dec, and phase goes from 0 to 180
