amplitude
It is well known that amplitude modulation does not affect Fredholmness of Toeplitz operators.
      
The finite dimension of the global attractors for the systems of the perturbed and unperturbed dissipative Hamiltonian amplitude equations governing modulated wave are investigated.
      
A new feature extraction method using the amplitude fluctuation property of target HRRP for radar automatic target recognition
      
Actually, the amplitude fluctuation property of target HRRP also represents some feature information of the target.
      
Based on the scattering center model, a new feature extraction method using the amplitude fluctuation property of target HRRP is proposed in this paper.
      
Fast identification of digital amplitude modulation level at low signal-to-noise ratio
      
The planar spiral coil was connected as an amplitude modulation circuit.
      
A function of synchronous superposition of object complex amplitude reconstructed from N-step phase-shifting through one integral period (N-step phase-shifting function for short) was proposed.
      
In ideal conditions, the proposed method is a kind of synchronous superposition algorithm in which the complex amplitude is separated, measured and superposed.
      
The phase-shifting errors in N-steps phase-shifting phase measurement can be treated the same as the relative errors of amplitude and intensity under the understanding of the N+1-step phase-shifting function.
      
However, the amplitude of voltage would also increase by 40% in coils and turns.
      
The electromagnetic fields in the cavity are a type of standing wave in the ELF band and the variation of the amplitude versus frequency coincides with Schumann's resonance.
      
Within the structure mentioned, instead of complex modulation patterns, pulse amplitude modulation (PAM) combined with PO-CI spreading code is utilized.
      
Through PSD analysis, we can get the amplitude-frequency spectrum and drive frequency.
      
We present recent existence results of Cantor families of small amplitude periodic solutions for completely resonant nonlinear wave equations.
      
In CIEFCM, a tiny disturbance is added to a filial generation group using a chaos variable and the disturbance amplitude is adjusted step by step, which greatly improves the colony diversity of the immune evolution algorithm (IEA).
      
By analyzing the bifurcation plot, Poincare section plots and amplitude spectra, we found that the crack greatly influences the dynamic characteristics of the rotor-bearing system.
      
Amplitude-displacement and phase-displacement equations are deduced for non-ideal carrier wave and inductance parameters.
      
Considering that the traditional process method is an approximate one, a new method is presented to simultaneously obtain the amplitude and phase of output signal of sensor by simultaneity A/D and ellipse fit arithmetic.
