An Entity of Type: organisation, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

A shift invariant system is the discrete equivalent of a time-invariant system, defined such that if is the response of the system to , then is the response of the system to . That is, in a shift-invariant system the contemporaneous response of the output variable to a given value of the input variable does not depend on when the input occurs; time shifts are irrelevant in this regard.

Property Value
dbo:abstract
  • A shift invariant system is the discrete equivalent of a time-invariant system, defined such that if is the response of the system to , then is the response of the system to . That is, in a shift-invariant system the contemporaneous response of the output variable to a given value of the input variable does not depend on when the input occurs; time shifts are irrelevant in this regard.

  • 平移不變系統(shift invariant system)是时不变系统對應離散時間下的版本,定義為若y(n)是系統對輸入x(n)的響應,則y(n–k)是系統對輸入x(n–k)的響應。在平移不變系統中,某一輸入產生的響應和當時的時間無關,時間平移不會影響系統特性, (zh)
