Title: Mapping a NTF filter transfer function to a delta sigma architecture
Post by avlsi on May 5^th, 2013, 7:44am

Hi all,

I have designed a highpass butterworth filter of order 5 for NTF in DSM .
Now I would like to map this NTF filter transfer function to a standard DSM implementation like CIFF or CIFB.

I would like to know if there is any procedure to map the same.

Use Schreier's delta sigma toolbox for Matlab. It has routines for generating coefficients for different standard topologies(CIFF, CIFB).
