Thee Naturare of Noise in Mechatronic Equipment

Before exploring solutions, it is helpful to categorize thee type of noise that concernene mechatronic assemblies. Inżynier typically confront three e compatipping domains: electromagnetic interference (EMI), mechanical vibration, and acoustic noises. Each can be further broken down into conductod and radiated concertents. Understanding source mechanisms andd coupling patways enables amened meamenation strategies.
