störaussendung

Störaussendung, a German term, translates to interference emission or spurious emission in English. It refers to unwanted electromagnetic radiation that is unintentionally produced by electronic devices and equipment. These emissions can originate from various sources, including digital circuits, switching power supplies, and radio frequency (RF) components. Störaussendungen are a significant concern in electromagnetic compatibility (EMC) because they can disrupt the proper functioning of other electronic devices operating in the vicinity.

The generation of störaussendung is a consequence of the fundamental principles of electromagnetism. When electric currents change rapidly or are switched, they create time-varying electric and magnetic fields. These fields can propagate through space as electromagnetic waves, even if not intended for wireless communication. The intensity and frequency spectrum of these emissions depend on the design and operation of the source device. Factors such as circuit layout, component selection, and shielding play crucial roles in determining the level of spurious emissions.

Regulatory bodies worldwide set limits on the permissible levels of störaussendung to ensure that electronic devices do not cause harmful interference to other systems. Compliance with these regulations is often required for a product to be legally sold and operated. Manufacturers employ various techniques to mitigate störaussendung, such as filtering, shielding, and careful circuit design, to reduce the electromagnetic noise generated by their products. Understanding and controlling störaussendung is essential for the reliable operation of modern electronic systems.
