Analog Technologies: The Basics 

Before we get into the fancy stuff, we need to understand the basic techniques used in analog computers.
The fundamental concepts of all analog computers.
In math, independent input variables are commonly multiplied by constant values in the equation. Here's how we accomplish this in analog computers.
An analog computer wouldn't be much good if it couldn't perform simple addition.
Another typical element in mathematical equations is the addition of some fixed constant.
