Storingsruis

Storingsruis is a term used in Nordic electrical and communications engineering to describe unwanted disturbances or interference that degrade the performance of a system. The word is a compound formed from roots meaning disturbance and noise, and it appears in technical manuals, standard documents, and industry reports to denote irregular or external perturbations affecting signals, measurements, or control processes.

Storingsruis can originate from a range of sources. Electromagnetic interference from nearby equipment, radio frequency interference from wireless devices, power supply fluctuations, and electronic cross-talk between channels are common contributors. Physical factors such as mechanical vibration, temperature drift, and aging components can also produce storingsruis, which may be continuous or impulsive in nature.

Characterization and measurement of storingsruis rely on standard signal-analysis techniques. Engineers examine spectral density, waveform shape in the time domain, and statistical properties to distinguish noise from the desired signal. Tools such as spectrum analyzers, oscilloscopes, and network analyzers are used, with metrics including signal-to-noise ratio, noise figure, total harmonic distortion, and sensitivity to interference defined by relevant industry standards.

Mitigation of storingsruis involves both hardware and software strategies. Hardware approaches include shielding, grounding, proper cable routing, filtering, and isolation of sensitive components. Software-side measures may involve error correction, adaptive filtering, and discrimination algorithms. In complex systems, a combination of mitigation techniques is used to maintain signal integrity and system reliability.
