Good day.
I'm a beginner in designing Delta-Sigma ADCs and I stumbled upon the SDtoolbox in Mathworks. As I try to implement the various demos included(SD2demo.m to be exact), I began to notice the following:
So my question is, how do I interpret what nper and N are? What is their use? Why not use the input frequency of the desired signal instead? Also, what is the baseband? why use it for computing the oversampling frequency? As I recall, the oversampling frequency is the nyquist frequency multiplied to a certain oversampling ratio(which is in this case, R).
Thank you and I hope to hear your thoughts on this.
