As the name implies, this EMI is produced by naturally occurring phenomena. Naturally occurring EMI comes from a variety of sources such as lightning, electrical storms, or even cosmic noise, to name a few. The following is a more detailed examination of these three criteria of EMI categorization. The frequency range of the interference or the bandwidth of the EMI.
Length of occurrence or the duration of the EMI. We categorize EMI into its various types with regard to three determining factors:
Types of Electromagnetic Interference (EMI) These characteristics vary and are dependent on the method and source producing the disruption.Īs I am sure you are aware, EMI is an unwelcome phenomenon, and its mitigation or elimination is paramount to device performance and functionality. In addition to the two category types, EMI has a veritable list of characteristics. However, like power loss, they should not be part of the design.Īlthough there are numerous sources of EMI, it fundamentally resides within two categories or source types: naturally occurring or human-produced. These various EMI or RFI (radio frequency interference) forms can manifest in a multitude of ways. Various forms of EMI can adversely affect circuits. Categories of Electromagnetic Interference (EMI) Although there is a myriad of disruptive phenomena that designers in the field of electronics must contend with, EMI is usually at the top of the preventative to-do list.
