Compute Phase Shift between two sampled sine waves using C code

Provide C code usable on an embedded linux system to compute the phase

shift between two simultaneously sampled sine wave signals. Signals will be of different magnitudes and offsets. Samples will be of a window in real time that will include one or more periods of the sine waves. Number of samples may vary.

We are expecting an implementation of this function:

float phaseDiff(int *x, int *y, int numsamples);

The inputs x and y are integer arrays of values in millivolts. The return value is

the phase difference (either radians or degrees).

We are currently using the following matlab code to do this:

Dear Sir/Madam In order to calculate the phase shift, it is required to perform Fourier transformation on the signals. Therefore, an FFT library must be used. Usually, FFTW is used ([url removed, login to view]), unless some More
