Hi all,
I want to design a digital delta-sigma DAC. It includes a pulse density modulated module and RC low-pass filter.
The pulse density modulated module is a Delta-Sigma type (one adder and one substractor). But why use Delta-Sigma type (i.e. how to understand it)? Is there any good tutorial on digital Delta-Sigma?
Best regards,
Davy
