Calculate phase difference of two signals

WebApr 6, 2024 · @OliverCharlesworth I've tried using xcorr (cross-correlation), the fft function, and the hilbert function in an attempt to calculate the phase difference, but the values do not match up with the theoretical values at the same frequency. I expected values less (more negative) than what I had received. At low frequencies, the hilbert transform came … WebThat means, those two sinusoidal signals are out of phase. If the Lissajous figure is in circular shape, then the phase difference between the two sinusoidal signals will be $90^{\circ}$ or $270^{\circ}$. We can calculate the phase difference between the two sinusoidal signals by using formulae, when the Lissajous figures are of elliptical shape.

WebJan 23, 2024 · Phase unwrapping works by examining the difference of two successive phase values to determine if a "jump" has occured and correct for it. In your case, the jump would occur as $\phi$ tends to $180^\circ$ and then wraps around back to $0 ^\circ$ instead of keep "walking" the circle towards $360 ^\circ$ (Or, the other way around the circle). WebUse two PLL. Generate as low frequency as possible, from both of the high frequency signal. Let's say 150MHz -&gt; 15MHz. The phase difference will remain the same between the two low frequency signal. Then measure the phase of these slow signals. (XOR them or use any other logic)
