The sum of this series is the coupling coefficient for fixed-ratio schedules:

To derive the coupling coefficient, the probability of the schedule not having ended, weighted by the contents of memory, must be integrated.

The coupling coefficients for all of the schedules are inserted into the activation-constraint model to yield the predicted, overall response rate.

In electronics an inductively coupled circuit with a low coupling coefficient is often called loosely coupled.

The coupling coefficient, k, is between 0 and 1.

Alternatively, one may introduce a coupling coefficient and rewrite eqns (4.52) and (4.53) in the form.

In the area near the trench, the coupling coefficient is high, which could act as the source of the large tsunami.

Qualitatively the electromechanical coupling coefficient, k, can be determined as:

The mutual inductance also has a relationship with the coupling coefficient.

The fraction of the field that does couple is called the coupling coefficient.
