I'm interested in deepening my understanding of analog computational circuits. I'm looking for someone to collaborate with to pursue this interest. To begin with, it'll be great if someone can point to me to the author of the computational circuits section. Thx.

 

Analog computation circuits are mainly limited to performing basic adding, subtracting, multiplying, dividing, integration, and differentiation of analog (voltage) values. In the past they were mostly used in the simulation and stabilization of electro-mechanical systems. Today the only remnant remaining of that is the various op amp circuits that are still occasionally used in some control systems.

Prior to the electronic versions there were also analog mechanical computers. The Norden bomb sight from WWII is a famous example.

You best way to find information is likely just to Google "Analog Computers".
