During the analyses the following acoustic variables were assessed: call duration (in second = s), interval between consecutive calls (s), number of notes (notes/call), duration of notes (s), number of pulses per note, duration of pulses (s), dominant frequency
(Hz), modulation of dominant frequency
(Hz) and repetition rate (notes/s) (Kok and Kalamandeen, 2008; Kohler et al., 2017).
"Acousticians define the frequency that carries the higher energy level as the 'dominant frequency
' of a particular spectrum," Yan wrote.
In anurans, acoustic properties (i.e., dominant frequency
, note duration) are usually influenced by body size (Cocroft and Ryan, 1995; Tarano, 2001; Wang et al., 2012), suggesting they could facilitate decision-making related to male-male competition and/or female choice.
In Asia-Pacific where C-band is the dominant frequency
, how do you see high-throughput (HTS) developing, and what are the drivers to encourage a widespread adoption of HTS in this region?
Comparatively speaking, when the open mode takes place, the corresponding dominant frequency
of the transmitted P-wave will drop.
In addition, quantification of tremors is often performed using a dominant frequency
, which is calculated using the power spectral density function or root mean square (RMS).
There are previous works on detecting the heartbeats of a human body through a wall with UWB impulse radar [7-9], but these studies deal with radar signals in the frequency domain, so these methods can only express the dominant frequency
component during a particular time interval and cannot provide time domain characteristics.
(1, 15) Since seismologists began observing seismic waves from earthquakes, the existence of an ambient seismic wave field with a dominant frequency
of about 0.15 Hz was firmly established.
Also, the frequency domain based intensity is normally linearly matched to the time domain based intensity, but it has an additional benefit which is the ability to find a dominant frequency
range on the frequency domain [22,23].
The second take away from Figure 3 is the dominant frequency
content of road excitation input.
If the number of poles is 2, the position of the feature will be numerically equal to the slip value given in percentage and will not be covered by dominant frequency
