ˈwaveform
Also wave form, wave-form.
[f. wave n. + form n.]
The shape of a wave at any moment, or that of the graphical representation of a (usu. periodically) varying physical quantity; a wave regarded as characterized by a particular shape or manner of variation, esp. a varying voltage.
1845Rep. Brit. Assoc. Adv. Sci. 1844 i. 340 The wave of the first order has a definite form and magnitude... This wave-form has its surface wholly raised above the level of repose of the fluid. 1846W. R. Birt in Rep. Brit. Assoc. i. 138 Should the rarefying process cease,..not only will the wave-form be continued, but also the wave-motion. 1889Welch Text. Bk. Naval Archit. iii. 58 It is only the wave form which advances, and not the water composing that wave. 1903Whittaker's Electr. Engineer's Pocket-Bk. 104 The effects produced by the various wave forms may be calculated by summing the effects produced by each component having this peculiar form. Ibid. 108 The wave form of an alternating E.M.F. 1923Proc. R. Soc. A. CIII. 84 The term ‘wave-form’ is used throughout as a convenient abbreviation for the ‘temporal variation of the electric field’. 1947Crowther & Whiddington Science at War 15 A cathode ray tube would be suitable for finding the wave-form of the atmospheric. 1958Engineering 31 Jan. 160/1 Electrical waveforms can be generated electronically and fed to the speaker which transforms them into ‘artificial’ sounds. 1968Brit. Med. Bull. XXIV. 251/2 They established that the breathing waveforms contain at least four significant components, having approximate frequencies of 0.27, 0.12, 0.07, and 0.03 cycles per breath. 1977Rolling Stone 24 Mar. (Advt.), These new speakers come with a test record that lets you pinpoint the output level where your particular amplifier begins to clip the peaks of the musical waveform. |
