Fit the Analog anti-imaging filter
Hsiang-Yu Huang
We measure the analog anti-imaging in LHO:68106, then fit the data by iirrational package. A fit of this analog anti-imaging fitler gives ZPK below.
| Fit Zeros | Fit Poles | Fit Gain (k) | Fit delay |
|
[68.667+ 6.636e4j 68.667- 6.636e4j 3.524e4- 0.j] Hz |
[4.971e3+ 9.613e3j 4.971e3- 9.613e3j 7.635e3- 0.j 4.322e4- 0.j 4.334e4- 0.j] Hz |
