Signalwege

Signalwege is a German term that translates to signal paths or signal routes. It is used in several disciplines to describe the route a signal takes from source to destination, including how it is generated, transmitted, and interpreted. Depending on the context, the term can refer to electronic, biological, or transportation signaling.

In biology and biochemistry, Signalwege (signal pathways) refer to networks of molecular interactions that transmit information inside a cell. They start at a receptor or sensor, pass through intermediate molecules such as kinases or second messengers, and lead to a cellular response such as gene expression, metabolism, or cell division. Pathways often interact, form feedback loops, and can be activated by different stimuli; examples include the MAPK/ERK, PI3K-Akt, and JAK-STAT pathways.

In electronics and signal processing, a Signalweg denotes the physical or schematic path of an electrical signal from input to output. It includes components such as amplifiers, filters, converters, and interconnections. Understanding the signalweg is essential for assessing noise, distortion, bandwidth, and overall system behavior.

In railway signaling, the term Signalweg describes the sequence of signals, switch points, and interlocking logic that governs a train's movement along a route. It encompasses how a route is set and released, how signals reflect the occupancy of sections, and how safety rules are applied to prevent conflicting movements.
