I will show the comparison of a first order Sigma Delta DAC and first order Sigma Delta ADC and then use the ADC to further detail how the Sigma Delta structure provides noise shaping which results in increased precision once the higher frequency spectrum is filtered out. I will then show how this is expanded to higher order structures and provide references for further reading.

I will show the comparison of a first order Sigma Delta DAC and first order Sigma Delta ADC and then use the ADC to further detail the operation for sigma delta modulation. I will also show how this is expanded to higher order structures.

How do I know this? I've implemented higher order sigma delta modulators for data converter and fractional frequency synthesizer applications. I teach courses on DSP and Python related to wireless comm through dsprelated.com and the ieee with new courses running soon! These graphics are out of my "DSP for Software Radio Course" which includes Sigma Delta modulation and more detail in noise shaping.
