What is the way to get the phase between to harmonic signals in labview. I'd like to avoid FFT, and use hilbert transform with hanning window. Something like this phase = - angle(sum(SigA * Hilbert(SigB) * Hanning)), where hilbert has SigA as real part and actual hilbert transform as imaginary, like in Matlab. I tried Labview functions and get garbage. Please help. Thanks.
