Sentence examples for in a frequency interval from inspiring English sources

The waveguide structure operates in a frequency interval that is commonly shared by both transverse-electric (TE) and transverse-magnetic (TM) polarizations.

The analysis of isothermal segmental relaxation patterns recorded in a frequency interval of 10−3 60 Hz indicates the appearance of two distinct contributions, which find correspondence with observations by broad band dielectric spectroscopy on the same systems.

Previous studies have shown that wettability has an effect on the complex permittivity of rock in a wide frequency interval.

To overcome the heterogeneous frequency resolution, the easiest and most straightforward approach is to integrate the power spectral density (PSD) in a certain frequency interval and use the integrated power as the metric for comparison.

In this section, we introduce an orthogonal transform that enables transforming an or-thonormal family of signals into another orthonormal family, the elements of which all have the same energy in a prescribed frequency interval.

The nMSE, which is computed in the time interval and in the frequency interval, is the average of a number of time-frequency values, giving the cost function: (2).
