Does IPP contains Butterworth filter with arbitrary attenuation at the cut-off frequency?

[JohnSilver]

HI ALL,

I am using Butterworth filter. 

It has -3dB at cut-off.

I need a low pass filter where attenuation at cut-off frequency can be specified.

I didn't found it in IPP.

Maybe I am missing something or maybe I need to use another library?

Thanks in advance

Have checked IPP developer reference IPP iirgenlowpass-iirgenhighpass ?

Butterworth filter having a fixed attenuation of -3 dB at the cut-off frequency is based on the design characteristics of Butterworth filters. This is a fixed characteristic and cannot be changed without altering the fundamental nature of the Butterworth filter.
