摘要: By utilizing the second and fourth order linear prediction errors, a novel estimator for a single noisy sinusoid is devised. The frequency estimate is obtained from a solving a cubic equation and a...关键词: frequency estimation linear prediction single sinusoid ...
There is also a bandpass filter that removes part of the stray light. Moreover it allows to check that the detected light is truly SHG: by tuning the fundamental wavelength until the SH wavelength falls out of the passband of the filter and checking that the detected signal vanishes. During...

The impulse response of a generalized fractional second order filter of the form (s 2α + as α + b)−γ is derived, where 0 < α≤ 1, 0 < γ < 2. The asymptotic properties of the impulse responses are obtained for two cases, and within these
This method applies an anti-aliasing filter based on an order-8 Chebyshev type I infinite impulse response (IIR) filter [142] before decimation. 15 The observatory refer to the site and it is indicated by one letter, like L for Livingston. The addition of a number after the letter to ind...
Equation (1) is given as a function of the radius of the sphere and wavenumber for the fundamental wave in vacuum. The arc length is fixed to 8.8 µm at the equator. Amplified Ti:S laser � Filter 2� PMT Filter Figure 1 | Periodic molecular pattern on the sphere surface. (a...
Figure 8 shows the pole–zero plot of the second-order IIR filter Gk(z) shown in Equation (17). Two pole–zero pairs are of mirrored layout in the z-plane. The pole–zero pair lying in the upper half of the z-plane is mapped to the real frequency in the frequency domain, i.e....
Equation (12) becomes the transimpedance transfer function of a second-order bandpass filter: Vout Iin = sC1 R2 R4 1 + s(C1R2 + C3R4) + s2C1C3R2R4 (13) By choosing Z1 = R1, Z2 = 1/sC2, Z3 = R3, Z4 = 1/sC4, Equation (12) becomes the transimpedance transfer function of ...
Femtosecond pulses of vertical polarization are adequately attenuated with a neutral density (ND) filter and coupled into GaN waveguides with their polar axis vertical. The out-coupled signal is vertically width in order to dominantly excite the fundamental mode in the y-direction. The efficiency of...
