So I'm doing some digital signal processing. I have a a current and a voltage signal that I am multiplying together and then filtering through a lowpass filter to get a signal that equals A*B*cos(phi)/2. At this point I want to find phi, so I need the inverse cosine function.
Unfortunatly I'm having troubles trying to write a cordic algorithm because I'm confused starting with a polar coordinate system. Everything I've read only shows rectanglular coordinates. This is my first time doing any sort of dsp so I would appreciate any help or advice.
