1 интергармоническая частота
интергармоническая частота
Любая частота, не кратная основной частоте.По аналогии с порядком кратности гармоник порядок интергармонической частоты основан на отношении к основной частоте. Если это отношение меньше единицы, то такую гармоническую частоту называют субгармонической. В соответствии с рекомендацией МЭК порядок интергармонических частот обозначается буквой «m»

interharmonic frequency
frequency which is a non-integer multiple of the reference fundamental frequency
NOTE 1 By extension of the harmonic order, the interharmonic order is the ratio of interharmonic frequency to the reference fundamental frequency, this ratio is not an integer (recommended notation " m ").
NOTE 2 In the case where " m 1" the term of sub-harmonic frequency may also be used (see IEV 551-20-10).

fréquence interharmonique
fréquence qui est un multiple non entier de la fréquence fondamentale de référence
NOTE 1 Par extension du rang harmonique, le rang interharmonique désigne le rapport de la fréquence interharmonique à la fréquence fondamentale de référence. Ce rapport n’est pas un entier (notation recommandée « m »).
NOTE 2 Lorsque « m < 1 », le terme de fréquence sous-harmonique peut également être employé (voir VEI 551-20-10).

2 частота гармоники
частота гармоники
Частота, кратная основной частоте.
Примечание. Отношение частоты гармоники к основной частоте называют "порядком гармоники".

harmonic frequency
frequency which is an integer multiple of the fundamental frequency
NOTE The ratio of the harmonic frequency to the fundamental frequency is the harmonic order (notation: h).

fréquence harmonique
fréquence qui est un multiple entier de la fréquence fondamentale
