This is a block diagram of a simplified Delta Sigma ADC.Summary
This is a block diagram of a simplified Delta Sigma ADC  and is my own work drawn using "Inkscape" a free svg editor.
It was drawn to illustrate a description of the functioning of the so-called Delta Sigma ADC which appears in the
overall article on Delta Sigma modulation. This description was first uploaded by me and has since been nit-picked by 
others but the general sense and much of the text  remains much as I first wrote it. I say so-called Delta Sigma because 
being British I am used to interpreting the mathematical symbols for the process, ∑δ or ∑Δ  to read sigma delta. This is 

why sigma delta appears in the diagram. Given the amount of work undertaken by me I hope others will allow me my small foible.
