Inputseitiger

Inputseitiger is a German adjective used in technical contexts to describe something that pertains to or occurs on the input side of a device, circuit, or system. The term is formed from the English loanword Input combined with the German suffix -seitig, meaning “on the side of.” In many contexts, the more standard German equivalent eingangsseitig is used, but inputseitig appears in various engineering texts and datasheets as a direct loanword variant.

In practice, inputseitiger refers to components, effects, or measurements located at the input interface. Examples include inputseitige Impedanz (impedance on the input side), inputseitige Störungen (interference at the input), and inputseitige Filter (filters positioned at the input). The unilateral distinction is often made to separate phenomena or design considerations from those on the output side, described as ausgangsseitig or inputseitig in contrast with ausgangsseitig.

Usage and style notes: inputseitiger is more common in technical writing that adopts Anglicisms or rapid terminology from electronics practice. For clarity and wider acceptance, many writers prefer eingangsseitig or Eingangsseite when working in formal German, especially in educational texts or standards documents. When using inputseitig, readers should interpret it as a location-based qualifier tied to the device’s interface rather than to a functional division inside the system.
