Comparison of reverberation time T30 in the frequency function
for in situ investigations and an ODEON computer simulation
A typical frequency function
from a GE 1.5 wind turbine is shown in Figure 6.2.

of iPOWER for [gamma] = 0.15, and other pulses at [alpha] = 0.22.
With a high frequency function
, the tna hyper-detect[R] 5 provides stable operation for optimum sensitivity and consistent performance when inspecting products.
Excel can calculate this with the FREQUENCY function
"The Fix Frequency function
saves a lot of work," explains Mig Cardamone, Director of Sales and Marketing at Sennheiser Middle East.
The analytical signal, amplitude function, phase function, and instantaneous frequency function
can be obtained by using the Hilbert-Huang transform.
In the past few decades, algorithms for window function selection are developed, such as adaptive smoothing method in  and least square estimation for frequency function
In order to apply this method in actual practice, it is necessary to identify the frequency function
of system transfer because of the amplitude and phase frequency characteristics [10, 11].
Here, f(D) is a continuous frequency function
for the log-normal distribution, [[sigma].sub.0] is the standard deviation for the log-normal distribution, [D.sub.M] is the median diameter, and [D.sub.max] is the maximum drop diameter.
