Thanks for addition to my circuit. I tried it out and unfortunately the results don't seem to make much sense. The amplitude part works perfectly. The phase, however, jumps around and is consistantly too high in value. Presently I am inputing a 4v sine wave @ 1 khz. Channel 0 is directly from the

We are getting there ... 136 and -223 degrees are actually two versions of the same value modulo 360 degrees. You can remove this problem by for example adding 360 to your result and compute the reminder of the division by 360. Or, an easier way to do that is, to add 360 to your result if it is

I have read every post regarding how to obtain the phase difference between 2 input signals of the same frequency. I am using Labview 7 and have simulated the signals into my vi and everything worked great. I then input a signal into the 2 channels and used an RC filter to induce a phase shift and
