To begin with, I want to measure the phase difference between the current and voltage of a signal having a freq. between 10Hz to 100Khz ( I would not mind measuring the same for freq. going up to 1Mhz, if possible using simple "junk box" type components )
To give an idea about my "junk box", I do have a few 74HC4046, XTALs, PICs ( 16F and 18F ).
What I don't have are >30Mhz PLLs, CPLDs, prescalers etc.
1. How do I go about extracting the voltage and current "parts" of a signal?
My end target would be to measure L and C, separately, without worrying too much about their Q ( which you have to take into account when using the LC oscillator type meters )
2. Would the phase difference, caused due to the L/C, between the current and voltage "parts" be, in any way, dependent on the Q of the L/C?
3. From what I saw on the internet, I can carry out some good simualtions to test my queries in LTSpice - but I am just starting to learn it.
Would anyone mind setting up a quick simulation for me guiding me how to extract the V and I and measure the phase difference between them?
