pulsatance Physics.|pʌlˈseɪtəns|
[f. pulsate v. + -ance.]
The angular frequency of a periodic motion, i.e. 2π times its actual frequency.
1919A. Campbell in Proc. Physical Soc. XXXI. 81 In English a name has not yet been found for 2πn, where n represents frequency... I would suggest that it might be called ‘pulsatance’. The termination ‘ance’ brings it into line with words like inductance and reactance. 1946Electronic Engin. XVIII. 119 The displacement (D) at any point is a periodic time function of the form: D = ψ sin ωt..where ω is the pulsatance and ψ is the amplitude at any point in space. 1957Electronic & Radio Engineer XXXIV. 145/2 Equation (22) represents a phase vibration of natural undamped pulsatance ωn and damping factor ζ. |
