There was a time when I could "examine" a circuit board, and hand draw the circuit diagram...One connection at a time
Read the color codes and fill in all the values
The reason I mention this...Is because there are free circuit testing and design programs, out there
All you have to do is draw/input all the connection points and posts values
And the program will give you the output response
Change a value and the program will give you the new results
Works just like the stuff the big boys use for design work
I have a light duty version on my android tablet, just too tinker with on winter nights
PSPICE, but the device models still need to be accurate or the output only vaguely resembles the actual response.
