Title: problem about Schreier's Delta-Sigma Toolbox!!
Post by ls000rhb on Aug 31^st, 2006, 8:41pm

In the Schreier's Delta-Sigma Toolbox, there is two functions such as synthesizeNTF and realizeNTF.
I find that there is not a argument which notify the quantizer's bit number .eg. single bit or multibit.
for example the realizeNTF's usage is [a,g,b,c]=realizeNTF(ntf,form='CRFB',stf=1). NO ARGUMENT notifys the quantizer's or truncator's bit number!

i am confussed about it ,can any expert give me the answer!

NO Information about the quantizer's bit number ,I don't know the NTF which is aviliable for a single-bit sigma-delta modulator or a mulbit sigma-delta modulator . SOS!!
