What "passes" refers to frequency, measured in Hz.<BR/><BR/>If I understand you right we are in this case talking about "frequencies" refering to statistics.<BR/><BR/>In electrotechnics we are dealing with the term cutoff frequency.

Ich hab mich schon immer gewundert, wo der Spruch herkommt.<BR/><BR/>Bezüglich dem erwähnten Paper, die Idee ist im wesentlichen dass Gravitation einen Hochpass-Filter hat und das 'Gewicht' einer Masseverteilung davon abhängt wie homogen sie im Universum verteilt ist.
