Thread Subject:
Common phase in two signals

Subject: Common phase in two signals

Hi,

I am trying to generate a signal that is the result of two signals based on their phase,
suppose that I have two microphones in front of me capturing my voice, at this point the phase will be approximately the same between the two of them, because I am in front of them, but if I move to the right, closer to the right microphone and further away from the left one the phases will be completely different.
So, the question is, how can I create a new signal that is the result of the the two input signals when they share the same phase?

I have found this: http://www.mathworks.com/support/solutions/en/data/1-1CATV/?solution=1-1CATV

that is very similar, it calculates the difference in phase and amplitude of two signals, but I have no idea how can I make a function that keeps the parts of the signal with the same phase( in my case a variant in time signal)

You can't.

http://www.ehow.com/how_7424830_remove-posts-usenet-newsgroups.html

This newsgroup is unmoderated, so step 3 won't work. You could request that
the MATLAB Central administrators remove your post from the MATLAB Central
newsreader by contacting files@mathworks.com but that won't remove it from
all the other places that archive CSSM.
