I've to calculate phase difference between two sampled signals having the same frequency at any instant but not fixed frequency (40KHz - 50KHz).
1. Which algorithm should I use to calculate the phase difference between two signals to obtain accurate result ? FFT , Correlation or any other ?
2. Does the accuracy of calculated phase difference depends on the sampling frequency ?
I'm new to digital signal processing So, correct me if I'm wrong.
