Hi,
This is a question relating to DSP. I wasn't sure what section to put it in. (move it if you so wish)
I have the transfer function:
0.5 - 0.3 z-1
------------- = H(z)
1 + 0.25 z -1
I need to obtain a difference equation ( i.e in the form y(z)= )
My problem is I cant find in text books, or on the web, a simple explanation for converting said transfer function to a difference equation. (please note this is a difference equation not a differential equation).
I found the following link to be the most useful thing so far, (if you explore the site a bit). But I still don't understand how the process is done.

Thanks for any help anyone can provide,
