Signal Processing in the Density Domain

The last part of my five part column on Density Signal Processing came out this week.

The more I study modulation the more convinced I am that it is the future on mixed signal design.  I had a customer that wanted to rectify a signal, integrate its value for a fixed time, and digitize it.  I figured out how to do it with a single Delta Sigma Modulator and some digital logic. (two flip flops, a dual input logic gate and a counter.)
 
It makes sense to start at part 1 and read the whole series. I have had several people tell me that they had not looked at it this way before and it intrigued them.  It is a different way of looking at things but I think it is a good tool to have in your tool box.
