Spectral speech features may serve as noninvasive biomarkers for monitoring attention and executive function in major depressive disorder.

Researchers at Japan’s Kobe University Graduate School of Engineering are seeking to design a new technology that could significantly increase the efficiency of solar cells. The professor Kita Takashi ...

The autoregressive spectral estimator exhibits errors when the time series contains a transient spectral component. A variation in the choice of the autoregressive parameters minimizes these errors.

The basic function of any spectrometer is to take in light, break it into its spectral components, digitize the signal as a function of wavelength, and read it out and display it via a computer. In ...

When designing with interconnects, we're often concerned about issues such as crosstalk and reflections. We frequently ask for models from the manufacturers so we can run simulations to determine the ...

Lighting and display manufacturers must ensure their products are consistent in their light output, making them reliant on effective quality control methods. Their products must be validated, and ...

When evaluating the dynamic performance of precision analog-to-digital converters (ADCs) using fast Fourier transform (FFT) analysis, coherent sampling typically is used to accurately measure the ...
