  • Phase Measurement

    I'm designing a device to measure phase between two low-frequency sine
    waves using a phase-locked loop. The idea here is to measure the phase
    angle between an angular velocity stimulus and a torque response. The
    reason I'm
    using a phase-locked loop is that a PLL works well in noise.

    I find this device useful to me. I'd like to know if such a device would
    useful to anyone else.

    My questions are:
    (1) Would you or anyone you know use a phase measurement
    device in your work?
    (2) If so, what would you use it for and how?
    (3) What features would you like such a device to have?

    I will post a summary of replies

    Thank you for your time and answers.
