self-oscillationn.

Brit.

/ˌsɛlfɒsᵻˈleɪʃn/, U.S.

/ˌsɛlfˌɑsəˈleɪʃ(ə)n/

Origin: Formed within English, by derivation. Etymons: self- prefix, oscillation n.

Etymology: < self- prefix + oscillation n. Compare earlier self-oscillating adj. and later self-oscillate v.

Oscillation whose pattern is determined by properties of the oscillating system itself, rather than by the way in which energy is supplied to the system; esp. (Electronics) oscillation of the current in a circuit (such as a tuning circuit) due to the electrical properties of the circuit.
