[question][sigma-delta]synthesizeNTF.m in delsig toolbox

synthesizentf

someone who familiar with delta-sigma design could tell me:

q1.
i want understand the code segments about find optimal pole location,
how it works? or somebody can tell me where to find the related
information(or 'artical' or 'paper' or 'book')?


q2.
for a given spec: (osr,order<=8,H_inf),the NTF defind by synthesizeNTF.m
is the best one?

i'am a novice in delta-sigma design,may be the question i proposed is not
reasonable(ask wrong question),tell me, very thanks!!

how synthesizentf works

There is a book named "Understanding Delta-Sigma Data Convertors" tells you how the toolbox calculates the optimized poles. The material is in the chapter 8.1.1 "how synthesizeNTF works". The author, Richard Schreier of this book wrote the "delsig" toolbox.
