The frequency-dependent ratio of the motion-response phasor to the phasor of the excitation force.  1, record 3, English, - frequency%2Dresponse%20function

Record number: 3, Textual support number: 1 OBS

Frequency-response functions are properties of linear dynamic systems which do not depend on the type of excitation function. Excitation can be harmonic, random, or transient functions of time. The test results obtained with one type of excitation can thus be used for predicting the response of the system to any other type of excitation.  1, record 3, English, - frequency%2Dresponse%20function

Record number: 3, Textual support number: 1 OBS

Les fonctions de réponse en fréquence sont des propriétés des systèmes dynamiques linéaires qui ne dépendent pas du type de fonction d'excitation. L'excitation peut être une fonction du temps harmonique, aléatoire ou transitoire. Les résultats d'essai obtenus avec un type d'excitation peuvent donc être utilisés pour prévoir la réponse du système à tout autre type d'excitation.  1, record 3, French, - fonction%20de%20r%C3%A9ponse%20en%20fr%C3%A9quence

The [DFM] meter indicates the distortion factor, which is the ratio of the rms total distortion to the amplitude of the fundamental frequency, including harmonics.  2, record 5, English, - distortion%20factor

Record number: 5, Textual support number: 1 OBS

A common measurement is total harmonic distortion(thd) where the fundamental of a very low distortion sine-wave test signal is removed by a steep notch filter. The summed harmonics that remain are then measured as a voltage of the fundamental at the required test power of the amplifier.(When measured in this manner the term thd is not really correct since the distortion also has the amplifier noise added to it within the test passband. The correct term is distortion factor).(GRAEL, 1977, p. 326).  3, record 5, English, - distortion%20factor
