Notch filter with bais

I need to design notch filter with Vbais because I use a single supply.
Is some one can show me where I can find that?

Is the design of Notch Filter a problem, or the implementation with single-supply voltage opamp a problem? Please post back, so we can go into specifics.

Notch filter is like building a bandstop filter but with perfect nulls.

What is Vbais?

Notch filters can usually have gain 0dB at DC. Can you put a simple voltage divider from supply voltage to input of filter?
