If w0 is half way between the edges of a bandpass filter in the s domain, it won't be after bilinear transformation. The simplest way I know is too specify the band edges separately, not band center and bandwidth. How does the prewarped transform handle that?o Jerry -- Engineering is the art of making what you want from things you can get. �����������������������������������������������������������������������
