phase-lockv.

Brit.

/ˈfeɪzlɒk/, U.S.

/ˈfeɪzˌlɑk/

Origin: Formed within English, by compounding. Etymons: phase n.², lock v.¹

Etymology: < phase n.² + lock v.¹, after phase lock n.

Originally and chiefly Electronics.

transitive. To stabilize the frequency of (an oscillator or laser) relative to that of a stable oscillator of lower frequency by means of a circuit in which any variation in the higher frequency generates a phase difference which produces an automatic correction to that oscillation; to stabilize (a frequency) in this way; (more widely) to constrain the frequency or phase of (an oscillating phenomenon or system), esp. by means of a feedback mechanism; frequently with to. Also in extended use. Also intransitive: to be stabilized or constrained in such a way.
