    Detecting the resonant frequency of a LC circuit?

    Thanks audioguru! Your solution is great! I think so. If using the CD4046's phase detector II, we can lock up phase of two signal at 0 degree, and at the same time, the operating frequency of VCO is similar to the resonant frequency of LC circuit.  I need lock up at range of frequency of about...

    Detecting the resonant frequency of a LC circuit?

    Thank for your reply! I think that it is similar that, but phase of the voltage signal as a reference signal and phase of the current signal is a other input of PLL. In my project, I need to lock of phase between two signals - one is voltage and other is current.  Note that: the voltage is total...

    Detecting the resonant frequency of a LC circuit?

    Hi everyone! I need your helps . I have a project of induction heating. And I want to detect or sensing the resonant frequency of a LC circuit. This LC circuit is configurated as a parallel resonant, it includes two branks: one is L and other is C and they is parallel. I have an idea is: using a...
