dispersjonskjerne
Dispersjonskjerne refers to a concept in signal processing and communications, often related to the study of how different frequency components of a signal travel through a medium. When a signal with a range of frequencies propagates, each frequency might experience a slightly different delay or speed. This phenomenon is known as dispersion. A dispersjonskjerne, in this context, can be understood as a mathematical representation or a physical element that characterizes or contributes to this dispersive behavior.
In some applications, a dispersjonskjerne might be used to model the impulse response of a dispersive channel.
Techniques exist to compensate for dispersion. These often involve creating an inverse filter or a dispersjonskjerne
