ˌsuperregeneˈration Electronics.
[super- 6 b.]
Regenerative amplification in which self-oscillation is prevented by repeated quenching of the signal at an ultrasonic frequency.
1922Q.S.T. July 7/1 At a meeting of the Institute of Radio Engineers, Edwin Howard Armstrong on June 7th gave his new invention of super-regeneration to a tense and expectant audience. 1922E. H. Armstrong in Proc. IRE X. 244 This new result is obtained by the extension of regeneration into a field which lies beyond that hitherto considered its theoretical limit, and the process of amplification is therefore termed super-regeneration. 1943F. E. Terman Radio Engineers' Handbk. ix. 664 Receivers employing superregeneration find their chief usefulness in the wavelength range 0·5 to 10 meters. 1975R. L. Shrader Electronic Communication (ed. 3) xviii. 435/2 This type of superregeneration is often produced in RF amplifiers and is characterized by a wide band of spurious signals that it generates.
Hence superreˈgenerative a., employing or characterized by superregeneration; superreˈgeneratively adv.; superreˈgenerator, a superregenerative device.
1922Q.S.T. July 9/2 The super-regenerative amplifier. Ibid. 11/1 In the super-regenerator there is periodically sufficient positive resistance to wipe out this oscillation and hence it is not heard. 1934Wireless Engineer XI. 35/1 The receiver may be made to function super⁓regeneratively by increasing the s.g. voltage to the point of ‘squegging’. 1948Slurzberg & Osterheld Essent. Radio v. 232 Superregenerative detector circuits are used in light, compact, portable code receivers. 1959R. L. Shrader Electronic Communication xvii. 542 When coupled to an antenna, the superregenerator radiates a very broad signal. 1965Guardian 18 Jan. 16/3 The popular super-regenerative receiver..is the simplest and the cheapest on the market. 1975R. L. Shrader Electronic Communication (ed. 3) xviii. 434/2 A demodulator used in the past in the VHF range is the superregenerative detector. |
