21. Former Conrail locomotives can be spotted by recognizing phase differences in engine models and numbering. 22. This leads to a phase difference between the two components as they exit the crystal. 23. This combination breaks both inversion and time-reversal symmetries creating finite current at zero phase difference . 24. The evaluation of interaural phase differences is useful, as long as it gives unambiguous results. 25. Information on the phase difference ( if any ) and the reflected polarization is considered. 26. Detecting phase difference is very important in many applications, such as servo mechanisms, and demodulators. 27. Modern coriolis meters utilize the phase difference measured at each end of the oscillating pipe. 28. Therefore, as the wave exits the second slab the total phase difference is equal to zero. 29. The shape of the patterns can be resolved by analysing the interference pattern and phase difference . 30. The bottom of the figure shows bars whose width represents the phase difference between the signals.
