Signalkurven

Signalkurven is a term used in Nordic technical fields to denote the graphical representation of a signal's behavior. It commonly refers to plots that illustrate how a signal varies across time, frequency, or other domains, and serves as a visual aid in analysis and design.

In electronics and instrumentation, signalkurven includes time-domain waveforms such as a voltage or current versus time, and transfer curves that describe how the output responds to changes in input, including current–voltage (I–V) curves and amplifier transfer characteristics.

In signal processing, the concept extends to frequency-domain representations like magnitude and phase spectra, as well as impulse or step responses that characterize a system's dynamic behavior.

Practically, signalkurven are produced from measurements using instruments such as oscilloscopes, spectrum analyzers, network analyzers, or data acquisition systems, and are used to assess performance, verify specifications, or diagnose issues.

Related concepts include transfer function, impulse response, Bode plot, Fourier spectrum, and response curves. The exact meaning of signalkurven can vary by discipline, so context is important for interpretation.
