What does phase coherent mean?
Phase Coherence is a phenomenon where a constant phase difference exists between any two signals or waves of the same frequency.
What is a coherent signal?
So just what is a "coherent signal?" By definition, a coherent signal is a pair of optical signals that have the same frequency and that maintain a constant phase offset. Coherent modulation formats modulate the phase of the coherent light wave (Figure 1).
What is phase difference and coherence?
coherence, a fixed relationship between the phase of waves in a beam of radiation of a single frequency. Two beams of light are coherent when the phase difference between their waves is constant; they are noncoherent if there is a random or changing phase relationship.
How do you find the phase coherence?
Another way to check the phase is to record a short segment with the mics into a DAW, and then zoom in on the waveforms to compare the peaks and troughs. If the sound still seems to be lacking, play around moving the microphones and adjusting their distances from the sound source.
