| 21. | Thus the noise temperature is proportional to the power spectral density of the noise, P / B.
|
| 22. | That is the reason that we cannot use the energy spectral density as defined above in such cases.
|
| 23. | A measurement of the acceleration spectral density ( ASD ) is the usual way to specify random vibration.
|
| 24. | Many combinations of length scale and turbulence intensity give realistic power spectral densities in the desired frequency ranges.
|
| 25. | Random signals and noise : probability, random variables, probability density function, autocorrelation, power spectral density.
|
| 26. | Thermal noise is approximately white, meaning that its power spectral density is nearly equal throughout the frequency spectrum.
|
| 27. | Where G xy ( f ) is the magnitude of the spectral density is denoted as | G |.
|
| 28. | KZFT readily uncovers small deviations from a constant spectral density of white noise resulting from computer random numbers generator.
|
| 29. | A stationary random process does have an autocorrelation function and hence a spectral density according to the Wiener Khinchin theorem.
|
| 30. | For power spectral densities that decay less steeply than as, the integral in the numerator of does not converge.
