1944 Proc. IRE 32 181/3 The instantaneous angular velocity of the voltage phasor may..be of the form ωt = ω + Δω cos Ωt, where Ω is the angular velocity of the frequency deviation.
1962 F. de la C. Chard Power Syst. Engin. i. 4 Phasor impedance can be shown on phasor diagrams.., but it differs from phasor voltage and current in the important respect that its value is invariable with time.
1975 R. F. W. Coates Mod. Communication Syst. i. 2 The phasor conveys the essential information regarding amplitude and phase of a fixed frequency sinusoid.
1989 A. C. Davies Sci. & Pract. Welding (ed. 9) I. iv. 230 Phasors are rotating vectors. They are easier to draw than the more complicated wave form diagrams and are added or subtracted as are vectors.
2002 Appl. Optics 41 4579 We use a phasor analysis to examine the linear combination of the eigenvectors and show how improved performance can be obtained with a new configuration.
