A Dynamic Phase Meter for Program Material

A method is described for a metering device that is capable of measuring the phase angle relationship of two audio program channels. A treatment of alternate techniques is given. Mathematical analysis shows how dynamic measurement can be performed. In addition, a circuit is realized and described that incorporates there techniques and allows for an indication of phase differences over an 80dB range. Error sources of the meter are identified.
