Coming into this industry as a physicist, I’m trained to think of things in terms of reference potentials, image charges, and any number of other terms from electromagnetic theory. Once you’ve gone through the effort to produce your first PCB, and you find aberrant noise and EMI in your design, the importance of clearly...
