Could you regenerate your delta-sigma picture with a lower sampling rate
I noticed your recent edit to Delta-sigma modulation that added your photo: https://commons.wikimedia.org/wiki/File:Delta_sigma.png#/media/File:Delta_sigma.png

My frustration with this photo is that the sampling rate is way higher than each pixel's width, causing the vertical lines of the delta sigma representation to blur into each other so that they are just one giant orange blob. I realize of course that delta sigma sampling rate is going to be many times larger than the frequencies of the signal being sampled...however, imho your photo would have more educational value for this Wikipedia page if it used a sampling rate that wasn't too large. I would suggest the sampling rate should be low enough that there is at least one pixel space between each vertical line of the delta sigma representation.

 * Hi, @Em3rgent0rdr. Thanks for the feedback. I decided to add this to the page because I felt it was a more realistic visualization as opposed to the other visualization, which I have attached. I believe these two complement each other - the existing one for educational purposes as you say, and the one that I uploaded for more of a reference purpose. If I've misunderstood your request, please let me know. Thanks!
