Sentence examples for specified spectra from inspiring English sources

Based upon the discrete-time analog of the Wiener-Khintchine theorem, the autocorrelation of each of these component processes is obtained by inverse discrete-time Fourier transforming the specified spectra [ 13].

To generate the received data with a specified spectrum, a white Gaussian noise process is passed through spectrum shaping filter.

This constructs the frequency domain samples of the cognitive radio received signal with a specified spectrum shaping filter.

In particular starting from a specified spectrum in terms of SRS (Shock Response Spectrum) a time dependent discrete function, typically an acceleration profile, will be obtained to force the equipment by simulating the shock event.

Spectral imaging devices acquire images in many different wavebands, enabling the reflectance spectrum to be sampled at each pixel and hence the colorimetric representation of the image to be calculated for any specified spectrum of visible illumination.

Next, each of the time histories is appropriately scaled so that its response spectrum matches a specified design spectrum at selected periods.

Unless otherwise specified, NMR spectra were recorded at 40 °C on Varian 600, 800, and 900 MHz Unity-Inova spectrometers equipped with z-axis gradient cold probes.

In this study, we measured intracellular PpIX using fluorescence spectral intensity analysis, which allows an observer to check the specified PpIX spectra on a monitor by reading the PpIX fluorescence wavelength peak.

A wavelet-based procedure has been used to decompose a recorded accelerogram into a desired number of time-histories with non-overlapping frequency contents, and then each of the time-histories has been suitably scaled for matching of the response spectrum of the revised accelerogram with a specified design spectrum.

Then each wavelet packet vector is scaled suitably and iteratively for the response spectrum of the simulated accelerogram to fit a specified design spectrum.

The types of signal include both computer-optimised signals, which are designed to match a specified power spectrum as closely as possible, and pseudo-random signals, which have fixed spectra.
