Dear all,
I am trying to measureme the phase of the sine waveform.
I generated sine waveform and give to "spectral measurement" express VI to measure the magnitude and phase. The spectral measurement block gives magnitude and phase spectrum array with frequency difference of 1hz.
The input signal is 10hz sine waveform. so i checked the 10th element in the magnitude and phase array. I am getting the correct magnitude. but i am getting different values for phase measurement
For example, If the input signal having the phase angle of 0 degree, the spectral measurement gives as -90 degree. If input signal have the phase shift of 20 degree, the measurement blocks gives as -70 degree.
I cant able to find that how this -90 degree phase shift occurs.
Kindly help to solve it. Thank in advance.
with regards,
