How to find the phase difference between two identical signals if only their sum is given?
Show older comments
If I have two identical signal A and B but phase shifted, I know A=kB, where k is an amplification factor. I am given the signal C=A+B, how do I find the phase shift between A and B?
Assume that I don't know A or B, I just know they are identical. Thanks!

Do you know k ?

If A = kB, how is A phase-shifted? I'm assuming that k must be complex in this case? If k were really a real-valued amplification factor then A would not be phase shifted

Ah, a complex k might do it. I was thinking that Bill meant that B was amplified and then phase-shifted to form A, but Yes, that could be represented as a complex amplification.

Is the original signal real-valued (not complex) ?
