Title: Structure of DSM in delta-sigma toolbox of MATLAB
Post by pancho_hideboo on Apr 3^rd, 2011, 2:32am

The following new structures are supported in "realizeNTF()" and "realizeQNTF()" of newest Delta Sigma Toolbox(Version 7.3, July 3, 2009) of MATLAB which was developed by Richard Schreier.

(1) PFB ; Parallel feedback
(2) PFF ; Parallel feedforward
(3) Stratos ; A CIFF-like structure with non-delaying resonator feedbacks, contributed in 2007 by Jeff Gealow

Is there anyone who know these structure ?

For example, what is the difference between "PFF(Parallel feedforward)" and the "FF(Feedforward)" ?
