The ideal filter has an acausal (non causal) impulse response, which constrains its implementation. If your application does not requires returning to time domain...
First, the Fourier Transform (the frequency response of the system) can be recovered from the z-domain by evaluating the z-transform at the unit circumference with...

More than the feasibility, I suppose your question is related with the meaning of the resulting "strange" signal". If the the Nyquist frequency is 22.050 kHz and...
