A graphof dß/d omega for the transmission path over the range of frequencies of interest, where ß is the insertion phase shift expressed in radians at a certain frequency and omega the angular velocity expressed in radians per second. 2, record 1, English, - group%20delay%20characteristic

If dß/d omega is constant over the band of frequencies requied for a particular waveform the envelope of the waveform is transmitted without distortion and the time of propagation of a characteristic feature of the wave envelope, e.g. the crest, is equal to the group delay. 2, record 1, English, - group%20delay%20characteristic

Loi de la variation de dß/d omega pour une voie de transmission sur toute la gamme de fréquences dont il s'agit, ß étant le déphasage linéique, exprimé en radians, à une fréquence donnée, et omega étant la vitesse angulaire, exprimée en radians par seconde. 1, record 1, French, - caract%C3%A9ristique%20de%20temps%20de%20propagation%20de%20groupe

Si l'expression dß/d omega reste constante pour toute la bande de fréquences qui produit une certaine forme d'onde, la transmission de l'enveloppe de la forme d'onde se fait sans distorsion, le temps de propagation d'un certain point (par exemple la crête) de l'enveloppe étant égal au temps de propagation de groupe. 1, record 1, French, - caract%C3%A9ristique%20de%20temps%20de%20propagation%20de%20groupe
