1 асимметрия характеристики затухания полосового (режекторного) пьезоэлектрического (электромеханического) фильтра
- asymétrie d'une caractéristique d’atténuation d'un filtre passe-bande (d'un filtre coupe-bande)
асимметрия характеристики затухания полосового (режекторного) пьезоэлектрического (электромеханического) фильтра (At)
Относительная разность полос частот выше или ниже средней измеренных по одному уровню относительного затухания полосового (режекторного) пьезоэлектрического (электромеханического) фильтра, выраженная в процентах.
Примечание
Значение асимметрии характеристики затухания полосового (режекторного) фильтра определяют по формуле
,
где - полоса частот ниже средней частоты полосового (режекторного) фильтра;
- полоса частот выше средней частоты полосового (режекторного) фильтра.
