Hi Folks, In another thread Andy Kunz described a technique for placing an inductor on the PCB to help with reduce noise in the circuit. Now my question is "How do you learn about this sort of stuff?". Anyone have any pointers to any good books, web sites etc. which contain good practical advice on this sort of thing. In particular PCB layout, reducing noise, dealing with power supply problems etc. etc. Most of the books I've seen tend to deal with how to design the circuit but not much and how to make the thing work out in the real world! I know most of this comes from experience, but surely someone has tried to capture some of that on paper (or at least in bits on a web-site). I know that in my own field (Software) we have a similar problems but there are a few readable texts these days that at least try to provide the basics.... Help Andy
