Yesterday the temperatures were at -28 degrees Celsius in southern Finland. That’s really cold. This is so cold that is starts to cause problems in all sorts of devices. I had problems in starting my car. The battery felt weak. I planned to measure the voltage in it with a multimeter I have in my →
EDN magazine articele Ground loops by Howard Johnson (Signal Integrity) article starts with question why in audio circuit designers avoid ground loops at all costs, yet in digital products you normally see a solid ground plane holding hundreds of circuits. This is a good question and the article gives answers to that. Audio designers like →
If you thought that capacitor orientation only matters for polarized varieties like electrolytic capacitors you should read one article to make you change your mind. In PCB Layout Tricks—striped capacitors and more article Bruce Trump looks at why some film capacitors have a stripe printed on one end and why their orientation can matter. Careful →
