I need a explaination/schematics of how to measure the phase angle between the V and I of a DUT over a long range of frequency.
I am trying to construct a Vector Impedance Meter for my Senior Design Project. I am stuck on how to measure the phase angle. I try reading a couple of journals, but they never explain how to measure the phase angle.
I thot I already answered this. Put a resistor in series to measure the current, use the voltage across the device as the other measurment. Square up the voltage signals, put them thru an XOR gate, voila! phase angle.
Thanks for your answer. But an XOR gates gives a standard pulse (Logic 0 or 1). How is the output going to reflect the phase angle, considering the standard pulse the XOR gates gives.
