How to write Transfer function using QUARTUS II

Sir 1. Would anyone like to guide me to pen down a Transfer function [e.g (a2S2+a1S+a0)/(b2S2+b1S+b0) ] in Altera Quartus II 9.1 using Block diagram/ Schematic file? 2. How to ...

That's not a particularly a Quartus problem. Your question refers to digital signal processing basics. How s-domain transfer functions translate to z-domain, how z-domain functions are implemented as differential equations. Finally how to choose a suitable number format (preferably fixed point), how to code it in HDL.

IMHO, a good text book covering all aspects is digital signal processing with fpga by Maeyer-Baese.

P.S.: There are also special high-level tools like Altera DSP builder (based on Matlab). I think, you should refer to generic HDL signal processing.
