How to find the time delay using cross correlation between two sine waves?

[ppg224]

I am trying to find the time delay between two sine waves using cross correlation.

Both have:

sampling rate= 1kHz

number of samples= 1000

frequency = 10 Hz

The phase difference is 45 degrees but need to prove the cross correlation method to find find time delay, any suggestions please?

That's simple. First you have to get autocorrelation from phase 0 signal. Then crosscorrelate both sine signals. Next find maximum for correlation results. Difference between indexes of maximums is time delay(in samples) between sine signals.
