Hey and thanks for any info,
I'm trying to help out a friend who is starting an "Electronics Theory" class.
I took a similar class years ago. I remember only one thing... A box.
My instructor drew this box on the chalk board. It was 3 X 3 (left to right, top to bottom.)
This box; this is the root of my query and I don't know how to describe it.
The box looked like a tic-tac-toe game, i.e, 3 columns x 3 rows. It looked something like this:
|V|W|A|
|V|W|A|
|V|W|A|
Like V X A = W, or W / V = A etc... I think it had ohms in it as well...
Diagonally, backwards, up, down, left or right this little box described the outcome/ conversion.
Does anyone know what I'm talking about?
Thank you again for any help. This is one of those things that is just bothering me.
