matlab实现Delta-Sigma转换器杂音预测器

Delta Sigma converter spurious tone predictor

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 simulation, DS toobox is recommended: File ID: #19

 

Simulink DSM/DWA model can be found in: File ID: #23079
