词汇 phase-lock
释义

Definition of phase-lock in English:

phase-lock

verb
[with object]Electronics
  • Fix the frequency of (an oscillator or a laser) relative to a stable oscillator of lower frequency by a method that utilizes a correction signal derived from the phase difference generated by any shift in the frequency.

    〔电子〕锁相,相位同步

    Example sentencesExamples
    • By integrating this source with a delay line and a broadband, grazing-incidence toroidal mirror, the researchers generated odd phase-locked harmonics of the laser frequency up to very high orders.
    • At higher frequencies, unit responses from the BCSS appear to remain phase-locked even though failing to respond to every cycle of oscillation.
    • The frequency synthesizer has a double phase-locked loop with a high-frequency portion and an intermediate-frequency portion, each with one divider and one counter in a feedback branch.
    • They carry a single video channel and two audio channels, with channel selection by an I2C phase-locked loop programmable synthesiser.
    • In this image, 114-s light pulses were used at a repetition frequency of 160 Hz. Pulses were phase-locked to the sinusoidal voltage command driving the loudspeaker that delivered the sound stimulation.
