A pitch search method and device for digitally encoding a wideband signal, in particular but not exclusively a speech signal, in view of transmitting, or storing, and synthesizing this wideband sound signal. The new method and device which achieve efficient modeling of the harmonic structure of ...
The 3-periodicity obtained by direct Fourier transform(DFT)is well acknowledged as an important feature that can be used for distinguishing gene coding regions of a DNA sequence.An extended definition of signal-to-noise ratio(SNR)was presented.The statistical analysis of coding/non-coding regions ...

During the spring and autumn periods, daylength alone is an ambiguous indicator of the time of year but the progressive changes in daylength provide a certain environmental signal for the passage of the seasons. In order to locate the time of year accurately, a timekeeping mechanism in ...
At the same time, a subtracter 12 subtracts the level of a signal B to be inputted next and delayed by a bit from the level of a signal A that passed through a register 11 and inputted in advance by a bit. A multiplier 13 multiplies the subtracted output (A-B) by a positive ...
We use observations of the Luminous Blue Variable (LBV) P Cygni spanning seven decades, along with signal processing methods, to identify a periodicity in the stellar luminosity. We find a distinct period of $4.7 \\pm 0.3$ years together with shorter periods. The periodicity is a possible in...

Note the visible diverging lines parallel to the dominant period, corresponding to periodicity in the signal. The dominant periodicity of the units shown in (A) are as follows: 546.14, 409.60, 273.10, 273.10, 182.04, 56.50, and 34.86 s. To quantitatively assess the extent to which neurons ...
