measurement of phase and magnitude of 2 analog signal

[yoda]

hai....i have project to calculate the magnitude of AC voltage input and the phase angle between the AC voltage input and the constant 1mA AC current. im using 50kHz frequency for both signal. my input current signal will be connected to PIN_A1 and my input voltage signal will be connected to PIN_A0.

for voltage signal, i have to use ADC to get the magnitude. for current signal, since it is constant, is it possible for me to just write current value as 1mA in a program and no need to detect it since it is constant value?

for phase angle, my general idea is to use CCP1 (current) and CCP2 (voltage) where the delta_time is different time between CCP1 and CCP2 and the period=new_CCP1-old_CCP1

phase=(delta_time/period)*360.0

in programming, is it the best way for the PIC to get the phase angle first or do the calculation to get the amplitude of the voltage?

please help me...i'm new in programming

i have another problem, to use ADC, i need to connect the input signal to the analog pin rite? but to get the phase of same input signal, by using CCP1 or CCP2, i need to connect the input signal to the CCP1 or CCP2 pin (pin no 16 and 17 PIC16F87A)

can u guy help me how to solve this kind of problem.
