Sigma Stat

This toolbox allow the simulation of sigma-delta modulators. considering the most important building block non-idealities. Moreover, it provides functions for evaluating the sigma-delta modulator performance.

Matlab codes are provided for min-max optimization for loop-filter design in delta-sigma modulators.The MATLAB codes are based on our recent paper:M. Nagahara and Y. Yamamoto,Frequency-Domain Min-Max Optimization of Noise-Shaping Delta-Sigma Modulators,to appear in IEEE Trans. SP, 2012.A draft...

This file contains functions for:- estimating the quantizer noise from DSM and- estimating the mismatch noise from DWA-DAC.Both (time-domain) models generate noise estimate for arbitrary input vector (dc, sinusoid, n-tone, sawtooth etc.).Applicable to bandpass DSMs and bandpass DWA.For...

The algorithm takes in a 1-D signal and finds the Gaussian derivative of it with the given kernel size and sigma, to provide the zero crossings. The zero crossings are then analyzed to give peaks and valleys. In order to remove very closely situated peaks and valleys, a width (provided by the...
