average power

[stickz]

Do anyone has of know how to make a vi that can take signals from 2 channel. one being currennt and the other voltage and calculate the average power.  The calculation can not use FFT, or freq to help calculate the power. 

example :

(p1+p2+ ... +px)/ x

[Ian_Ren]

Since

P=I*V

Can you use

P=SUM(I(t)*V(t))/N?

Where I(t) and V(t) are the time domain signals, and N is the size of the I(t) and V(t).
