[IEV number 314-08-03]EN
phase modulation
process by which the phase of a carrier wave is varied, relative to a reference sine function, according to a specified law
NOTE – The result of this process is a phase modulated signal.

modulation de phase
opération par laquelle la phase d'une onde porteuse, par rapport à une fonction sinusoïdale de référence, varie selon une loi spécifiée
NOTE – Le résultat de cette opération est un signal modulé en phase.
