koppelingspunt

Koppelingspunt is a Dutch term used to describe the point at which two systems, components, or networks are connected to allow transfer of energy, information, or influence. The concept is generic and refers to an interface or junction rather than a single physical object, and it is used across multiple technical disciplines.

In electrical engineering, the koppelingspunt is typically the node where a source, a network, and a load meet. The electrical characteristics at this point, such as impedance and noise, strongly affect signal transfer and stability. Coupling between parts of a circuit can be direct or achieved through components like capacitors, transformers, or inductors, which shape bandwidth and isolation.

In mechanical engineering, the koppelingspunt is the location where two shafts or components are joined by a coupling device to transmit torque and rotation. Correct positioning, alignment, and the stiffness of the coupling are essential to prevent wear and vibration. Different coupling types exist, including rigid, flexible, and universal couplings, each suited to specific loads and misalignment conditions.

In control theory and systems engineering, the koppelingspunt denotes the interface between subsystems in a block diagram. It defines how signals, disturbances, and control actions pass from one part of the system to another and is characterized by transfer properties and coupling strength.

In radio and communications, the term may refer to the point where energy is coupled between an antenna and a transmitter or receiver, affecting efficiency and impedance matching.

Etymologically, koppelingspunt derives from koppeling (coupling) and punt (point). See also koppeling, interface, and coupling coefficient.
