Electronic engineering Definition and 47 Threads

Hello, I'd like to discuss what is called "ground loop". Consider the following scenario and call the set "C1 + S + C2" as "the system" -- Ground loop. As far as I can understand, the "noise/hum" at power grid frequency (50-60Hz) is actually due to electromagnetic processes external to "the...

Hello everybody. Nice to meet you ! I'm a young electronic engineer who wants to learn as much as possible about science. I love chemistry, physics, astronomy, mathematics, mechanics, etc. I'm sure I'll learn a lot with you. See you soon !

I'm currently building a thermal controller that can manage the cooling of various types of heat exchangers, and I'm specifically working on cooling a heat exchanger for an EV fast charger. I need to decide the optimal pump and fan speeds to achieve efficient cooling, but I'm not sure about the...

I am developing a Taekwondo body protector scoring system using a textile piezoelectric sensor. The sensor is designed to detect mechanical force and convert it into an electrical charge. However, it is sensitive to temperature variations, leading to potential inaccuracies and instability in the...
