You say you are a programmer, I assume you spent some time learning to program. Do you know programming theory, things like properties of sorting algorithms, calculatability, B+ trees, hashing, recursive decent and bottom-up parsers, properties of numerical algorithms, linear programming, AB-algorithm, etc? If you do: there just is as much to learn about electronics. Get a copy of H&H and read it, read it, read it. > I do admit I lack some of the math that is > necessary to get the correct values of components, but I > think that can come after I understand. I doubt that.
