You're probably familiar with the old-fashioned strings of holiday lights that go out completely if one bulb burns out. Although these lights cause hours of frustration during the holidays, they also ...

To understand a series circuit, visualize it. You can do that by making a drawing. Just draw a box, to start with. This box represents your circuit. Notice there is only one path: the perimeter of the ...

Last, but not least, we like to look at the I/O (Input/Output) circuits during EMI circuit board reviews. As a port of entry for external currents, I/O circuits are particularly vulnerable to threats ...

After the critical circuits, we like to examine the printed-circuit board (PCB) stackup. Like the schematic, board stackup decisions are often made prior to routing and placement, so this is a good ...
