In the case of techniques that use plasmas, such as Laser-induced breakdown spectroscopy (LIBS), the characteristics of the plasma and its expansion depends on the ambient pressure [16] and thermal distortions of the components of the instrument itself can affect its calibration or performance.
Understanding the whole process chain in view of different distortion potentials applied in each processing step provides the ability to control the distortion of the welded components.
However, this technique does not consider two important ultrasonic effects: the finite-time duration of the flaw UT signal coming from a defect and the distortion of the frequency components of the traveling wave-front due to the dispersion.
The development of flow structure also leads to distortion of directions of the component, which is observed at stratigraphic positions where the volume fraction of light-colored parts of the flow structure >30%.
This approach has successfully been applied in various other studies (Beste et al., 2010; Beste et al., 2008; Frank et al., 2007; Krämer et al., 2007) and minimizes possible distortions of the FRN component by the positivity on which it is superimposed.
Since the complete noise removal objective requires removal of both the impulsive noise and the low-level noise, these results suggest that as t increases, the Hampel filter allows more of the low-level noise to pass through the filter unmodified, offsetting the performance advantage of lower distortion of the sinusoidal signal components.
A case study from industry has been selected where it was observed that work hardening of machined surface leads to distortion of thin sections of the component.
Thus, for this hardware design constraint, the ACLR performance cannot satisfy the LTE test specification without the PAPR reduction scheme because of the non-linear distortion of active components, especially the PA.
Especially, after the digitization of the signal which has been subjected to nonlinear distortion, the harmonic component of the signal will invade the signal frequency band because of aliasing effect, causing additional distortion.
Consequently, it will degrade the ACLR and EVM performance because of the non-linear distortion of the PA and other active components.
