Hello, I use Matlab to make treatment of the signal. I will like to make a filter IIR having a frequency response which is the reverse of that of reference. How can I do that? |

Hi If you have the magnitude values then you can use them to design the required filter using FDA tool with arbitrary magnitude specification. If you know the coefficients of your reference filter then just swap numerator and denominator.
