Hello!

I am trying to recreate a plot from my sigmastudio parametric equilizer by drawing it in an external software.

What I am trying to get, but cant seem to find, is a 2nd order peaking filter transfer function by central frequency, Q factor and gain.

It would help me a lot if somebody would share it.

Thank you,

Filip

I was trying to plot a graph that i have pun in my parametric eq. but i didnt know the transfer function of the used filter to plot it. But i have got to the function by paralleling a band pass filter with a full pass filter and i got the correct transfer function.

The function is (for the absolute value)

|H(jw)| = sqrt((w0^2 - w^2)^2 + K*^2 (w*w/Q)^2) /sqrt((w0^2 - w^2)^2 + (w*w/Q)^2)
