motor-boatingn.

Brit.

/ˈməʊtəbəʊtɪŋ/, U.S.

/ˈmoʊdərˌboʊdɪŋ/

Origin: Formed within English, by derivation. Etymons: motor boat n., -ing suffix¹.

Etymology: < motor boat n. + -ing suffix¹, after boating n. Compare later motor-boat v.

1. The action of driving or travelling in a motor boat, esp. as a sport or leisure pursuit.

2. Electronics. Oscillation in an amplifier that is of such low frequency that individual cycles may be heard, giving a characteristic sound, and caused by feedback from the output to the input of earlier stages, often through a common voltage supply.

1930 J. H. Reyner Testing Radio Sets vi. 84 Back-coupling with a mains unit usually takes the form known as motor-boating. The oscillation set up is of a low frequency and gives a continuous ‘pop, pop, pop’.

1943 F. E. Terman Radio Engineers' Handbk. v. 409 A power supply having low internal impedance at low frequencies is also helpful in eliminating motorboating.

1965 G. J. King Radio & Audio Servicing Handbk. iii. 78 Decoupling prevents signals which could occur in an element common to two or more stages from getting back into the input circuits and causing oscillation or motorboating.

1996 IEEE Engin. Med. & Biol. Mag. 15 116/1 With this configuration, many amplifier stages could be powered from the same supply (battery) without oscillation (motorboating).
