Cross-Spectral Properties of Some Common Waveforms in the Presence of Uncorrelated Noise.

摘要

The magnitude coherence and phase for a number of common waveforms in the presence of uncorrelated noise is derived mathematically and presented graphically. Discussion is limited to waveforms resulting from the combination of no more than two traveling waves. The effects of the relative magnitude of the traveling wave components, as well as the uncorrelated noise, are seen. The effect of wave speed is also noted. Finally, the periodicity with respect to frequency, observed in the resultant plots, is shown to be significant and is a reflection of the relative wave speeds. A table summarizing the results is also presented.
