In this paper, we present the new frequency spectrum recurrence analysis technique by means of electro-encephalon signals (EES) analyses. The technique is suitable for time series analysis with noise and disturbances. EES were collected, and alpha waves of the occipital region were analysed by comp...
For the protection of incumbent users such as digital television (DTV), white space applications running on locally unused TV spectrum should be able to detect incumbent users at a low signal-to-noise ratio (SNR). Recent studies show that at a low SNR under high noise uncertainty, pilot dete...
The measured frequency noise spectrum of a pair of single-frequency Bragg grating fibre lasers is dominated by noise at audio frequencies peaked near 700 Hz which fades into a white noise floor above approximately 50 kHz. The measured white noise floor yields an estimated Lorentzian FWHM linewidth...
Noise by its very definition is random. It extends in various forms across the frequency spectrum, although not always in the same amplitude. Accordingly there are different categories of noise according to the frequency distribution:White noise: White noise is the type of noise that affects...
For example, white noise has a flat frequency domain spectrum, since each frequency is equally represented. Oscillator-Based Direct Sound Synthesis As we discussed early in this book, digital sound in the Web Audio API is represented as an array of floats in AudioBuffers. Most of the time, ...
spectrum surveillance system whose features are the measurement of signal strengh and carrier frequency,the location of transmitters,estimation of modulation parameters and the classifications of signals.This paper describes the design and implement a system to analyze and clasify the basic types of ...
Performance analysis of phase-coherent frequency-hopped spread spectrum systems in the presence of partial-band interference The authors analyze the performance of both hybrid and frequency-hopped phase-coherent spread-spectrum systems in the presence of additive white Gaussian n...

Our evidence is based on a number of psychophysical demonstrations that use stimuli with specifically tailored frequency spectra, constructed from white noise filtered in the frequency domain. Our evidence suggests that the visual system determines the average peak frequency of the spectrum and uses ...
When compared to the slow CWT, fCWT’s accuracy and noise-handling capabilities are not compromised by its highly efficient implementation. Small differences in the time–frequency spectrum can be seen at the edges. However, these differences are caused by MATLAB’s mitigation of edge artifacts (...
