Signaalivirta
Signaalivirta is a Finnish term used to describe the propagation of a signal through a system, i.e., the flow of signal energy or information from a source to an output. The concept is applied across disciplines such as electronics, telecommunications, control theory, and biology, each with its own emphasis on how signals travel and interact with components or pathways.
In electronics and electrical engineering, signaalivirta often refers to the current or energy carried by a
In communications and signal processing, signaalivirta describes the flow of a modulated signal through channels and
In biology and neuroscience, the term can denote the flow of signaling molecules or ionic currents within
In control theory and information theory, signaalivirta is used more abstractly to refer to the propagation
