whose frequency band is higher than that of the prescribed band signal; and a means for synthesizing the band signals after the noise reduction processing has been performed by the processor 250 and the noise reduction parts 204 and 214, and for creating an original image whose noise reduction ...
aFrom table 1 and frequency band range of the ECG signal and noise signal we know that the size of the baseline drift energy mainly concentrated in tier 8 wavelet decomposition of the approximate signal, in order to more thoroughly eliminate baseline drift, will the scale of wavelet ...
Imaging apparatus performing auto focusing function with plurality of band pass filters and auto focusing method applied to the same An imaging apparatus and an auto focusing method are provided. A plurality of focus signal values are calculated for a plurality of frequency bands of a ... SEC Lt...
A new type of circulators is presented which has been tested using circuits covering the frequency range from L- to W-band. This is, for the first time, a principle suitable for applications at 1.8 GHz as well as 77 GHz. At the lower frequencies ferrite drop-in circulators in microstrip...
Recently published Radiometric measurements of human subjects in the frequency range 480–700 GHz, demonstrate the emission of blackbody radiation from the body core, rather than the skin surface. We present a detailed electromagnetic simulation of
Demorest′s research has focused on radio telescope instrumentation and observations of millisecond pulsars. He has been a long-time participant in pulsar timing array projects, and was one of the founding members of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav). Dr....
The invention of the Fourier integral in the 19th century laid the foundation for modern spectral analysis methods. This integral decomposes a temporal signal into its frequency components, providing deep insights into its generating process. While this idea has precipitated several scientific and technol...
An object of the present invention is enhancing a capability of integration of a frequency finding circuit for finding a frequency of an input signal. A signal sampling circuit (21), sampling the input signal, utilizes a sampling signal (G) to convert the input signal into a sampled input si...
over filter frequency, cut or boost amount (usually up to about 15dB) and bandwidth (or 'Q'), so there are three controls per band. Most practical parametric equalisers have two or more bands that can be used at the same time to tackle problems in different parts of the audio spectrum...
Today, with the increasing penetration of microgrids, the degree of complexity and non-linearity of power systems has increased, causing conventional and inflexible controllers not to perform well in a wide range of operating points. In this paper, a sel
