shanon_uetian,
"Understanding Digital Siganl Processing" by Rick Lyons is available for free download. I thinks its available on this forum.
.
In addition to ythe bilinear z transform, search for "impuls invariant transformation". This transform is usefule when the phase and time domain responses must be preserved.
