WebJun 27, 2013 · A switching power supply can be designed to minimize its switching noise and can include output filters to reduce the noise, but it's impossible to know exactly what … WebElectrical Noise and Transients. Power quality. Electrical noise is the result of more or less random electrical signals getting coupled into circuits where they are unwanted, i.e., where they disrupt information-carrying signals. Noise occurs on both power and signal circuits, but generally speaking, it becomes a problem when it gets on signal ...
