signaalikierron
Signaalikierron is a term used in Finnish-language discussions of signal processing and cybernetics to describe the phenomenon of a system where a portion of the output is fed back into the input, creating a cyclical flow of information known as a feedback loop. The word combines signaali (signal) and kierron (circulation or loop). In practice, signaalikierron covers electrical feedback in circuits as well as informational or regulatory feedback in broader systems.
In electronic contexts, the behavior of signaalikierron depends on loop gain, delay, and phase shift. Negative
Not all literature treats signaalikierron as a distinct technical term; in many cases it is described using
