implementation of filter design

[harinii]

Hi all!!

We use a delay unit in the feed back path to implement z-1 in FIR/IIR system design. I am curious to know how to implement 'z' and positive powers of z if they appear in the tranfer function.

Sorry if the question seems a bit stupid :-(

Thanks

1) algebraically convert your transfer function so that all your z terms have negative exponents. then-->each z term represents a number of clock delays of it's input.
