A linear system cannot generate signal components that were not present in the stimulus spectrum, but any nonlinear system will produce harmonic distortion products in response to simple tonal stimuli, and more complex stimuli produce more complex distortion product spectra.
The effect of random error in multivariate analyses, with errors in a number of interrelated variables, can lead to more complex, serious distortions in the estimation of real exposure-outcome associations [ 11, 12].
It is known that the guard subcarriers decrease the spectral efficiency, while windowing reduces the delay spread tolerance and filtering is more complex and introduces distortion in the desired signals [30]. Figure 4 Single subcarrier PSDs of the OFDM and FBMC systems.
The spectrum of severity ranges from simple lacrimal canalicular laceration to more complex injuries, such as distortion, laceration and displacement in the whole lacrimal drainage duct.
Dsrc is mostly determined by the video source rate and the video sequence parameters (e.g., for the same encoding bit rate, the more complex the sequence, the higher the source distortion).
Notably, the distortion of aa-tRNA appears far more complex than anticipated earlier and extends throughout the tRNA molecule (Schuette et al, 2009).
However, Chinese character recognition for LPR application still faces many challenges, such as more complex structure, defective character, partial occlusion, and sensitiveness to affine distortion, noise, scaling, illumination variation, contamination, blurring, and so no.
And if more complex transformation such as three-order polynomial transformation is used, more general distortions can also be removed.
More complex models of formant contours will result in less error and consequently less distortion at the cost of a larger number of parameters.
Improvements were seen in the prevention of aliasing, phase and amplitude distortion, as well as in the noise reduction for sinusoidal and more complex input profiles.
