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.

frequency function," IET Microwaves, Antennas and Propagation, vol.

Frequency function 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 [5] and least square estimation for

frequency function in [6].

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.
