CE ÎNSEAMNĂ QUASIPERIODIC ÎN ENGLEZĂ?
Quasiperiodicity
Quasiperiodicitatea este proprietatea unui sistem care prezintă periodicitate neregulată. Comportamentul periodic este definit ca fiind recurent la intervale regulate, cum ar fi "la fiecare 24 de ore". Comportamentul quasiperiodic este un model de recurență cu o componentă de impredictibilitate care nu se pretează măsurării precise. Este diferit de conceptul matematic al unei funcții aproape periodice, care are o regularitate crescândă pe mai multe perioade. Definiția matematică a funcției quasiperiodice este un concept complet diferit; cele două nu ar trebui să fie confuze.
Definiția quasiperiodic în dicționarul Engleză
Prima definiție a quasiperiodicului din dicționar este aproape periodică. O altă definiție a quasiperiodicului are o creștere a valorii funcționale bazată pe creșterea variabilei. Quasiperiodic are, de asemenea, două perioade fără o durată comună.

For higher dimensions, another method of generating quasiperiodic patterns is
used. One begins with a periodic lattice in a higher dimension (e.g., for a one-
dimensional quasiperiodic lattice one uses a square lattice in two dimensions).

The Circuits and Filters Handbook, Second Edition
A quasiperiodic function is one that may be expressed as a countable sum of
periodic functions with incommensurate frequencies, i.e., frequencies that are not
rationally related. For example, X(t) — sin(f) + sin(2;tf) is a quasiperiodic signal.
