Получены оценки точности методов восстановления различных типов дискретных сигналов, в том числе линейного тренда, полиномиального тренда и периодического сигнала, для равномерного и нормального закона распределения джиттера.</p></abstract><trans-abstract xml:lang="en"><p>This paper presents reconstruction algorithms for non-uniform discrete-time signals with unknown locations.
