Origin: Formed within English, by derivation. Etymons: oscillate v., -or suffix.

Etymology: < oscillate v. + -or suffix.

1. A person who oscillates or vacillates in action or thought; a waverer.

2. Something that moves to and fro; a system or device that oscillates.In earliest use denoting an oscillating steam engine: see oscillating adj. 1b.

1849 G. G. Foster New York in Slices 126 He has obviated the only objections to the Oscillator, and is now engaged in manufacturing a gigantic engine on this principle.

1867 J. C. Merriam in Eighty Years' Progress U.S. I. 252/2 An oscillator costs less at the start, but requires more oil, and is of doubtful economy.

1881 Science 31 Dec. 622/2 Fig. 2..represents two of these oscillators, the sphere on the right oscillating vertically up and down; that on the left, on the other hand, oscillates horizontally from right to left.

1911 Sci. Abstr. A. 14 402 In the theory [of 1901] referred to the emission of the elements of energy is assumed to be excited by the continuous steady absorption of energy from the radiation incident upon one of the assumed oscillators. This the author [sc. Planck] now replaces by the assumption that the emission and absorption are entirely independent.

1936 P. M. Morse Vibration & Sound ii. 27 Every driven oscillator is mass controlled in the frequency range well above its natural frequency ν₀, is resistance controlled near ν₀.., and is stiffness controlled for frequencies much smaller than ν₀.

1970 G. K. Woodgate Elem. Atomic Struct. iii. 45 In trying to make a model of a one-electron atom out of three classical oscillators (one for each direction of polarization) we do not take account of the fact that the atom can emit many frequencies..whereas the classical oscillators emit only one frequency.

1973 Country Life 19 July 151/2 The best oscillators have a device which enables the degree of oscillation to be varied from a wide to a narrow throw.

1994 New Scientist 8 Oct. 39/1 All three oscillators move identically, but successive oscillators around the triangle ring are one-third of a cycle out of phase with each other.

a. An apparatus for generating oscillatory electric currents, or for generating electromagnetic waves by means of such currents. Also: a device for generating sound waves.local oscillator: see local adj. and n. Compounds. master oscillator: see master n.¹ and adj. Compounds 2a.
