The Delta-Sigma Toolbox includes nearly 100 functions which support NTF synthesis, modulator simulation (from an NTF or a structure), realization, dynamic range scaling, SNR estimation and more. The toolbox is well-documented via the accompanying DSToolbox.pdf manual.
For further information regarding the Toolbox and Delta-Sigma modulators in general consider purchasing "Understanding Delta-Sigma Data Converters, Second Edition" by Pavan, Schreier and Temes (ISBN 978-1-119-25827-8).

Requires

The Signal Processing Toolbox and Control System Toolbox are needed. The Optimization Toolbox is used in a small number of functions, but is not a necessity. Users should compile the simulateDSM.c and simulateESL.c files to speed up simulations.

Download	23 Feb 2020	2020.1	Corrected the "Required MathWorks Products" field in web listing
Download	23 Feb 2020	2020.0	Now includes functions to support the design of Polynomial-Based Filters: designPBF.m, frespPBF.m, impulsePBF.m, shiftPBF.m. Also updated ratapprox.m.
Zip Toolbox	5 Jun 2016	2016.1	Added demoLPandBP.m. Updated dsexample1.m and dsexample2.m
Download	4 Jan 2016	2016.0.0.0	Added designPBF.m (for designing polynomial-based filters using Hunter's method). Added dsexample*.m. Replaced simulateESL with simulateMS for simulating mismatch-shaping. Expanded dsdemo5.m (demonstration of mismatch shaping). Actually uploaded the delsig.zip file this time.
Download	29 Dec 2011	1.3.0.0	Incorporated Jeffrey Gealow's improvements which remove restrictions on the tdac argument in realizeNTF_ct and mapCtoD. Values such as [1 3] or [2 3] are now OK.
Download	6 Jul 2009	1.2.0.0	Added functions for realizing an NTF with a continuous-time loop filter and for handling quadrature modulators.
