Power Factor Meter

Dear Friends,
I am trying to design a digital "Power Factor Meter". I tried finding information for power factor meter on internet but couldn't get any. I would be very thankful if someone could just provide me the concept for designing this meter. I need only the anologue part design.

Thanks,

With best regards,
Garg

This is a microcontroller forum !?

That is good. Please let me know if you build one.
I suggest that you better discuss the design with us and develop the circuit step by step. First find out your requirements and then gather some information.
If you want the basics of PFM, then above material will be good enough.
