Improving signal quality

In an effort to improve signal quality by reducing baseline noise, a water-cooled particle impinger bar was installed immediately upstream of the path control probes. This bar directs a portion of the particulates around the beam path and reduces the interaction of particles with the beam. In this configuration, the TDL and extractive CO measurements agreed to within approximately 2% CO over a range of approximately 0 to 15% CO. The output of both instruments contains a noise band of approximately +1% CO. [Pg.322]

In vivo characterization is more suited to the assessment of CP biological performance, with studies tailored for the intended implant application. In vivo CP studies have been largely limited to electrode recording applications, where CPs have been shown to temporarily improve signal quality [52]. This is due primarily to nemal interactions, discussed further in Section 18.6. Future biological characterization of CPs must focus on in vivo, long-term studies in anatomically appropriate sites with on-going assessment of electrical performance. [Pg.727]

In robustness tests, peak measurementfanalysis parameters can also be considered. Such parameters are related to the measurement of the detector signal and they affect responses, such as peak areas, peak heights, retention time, and resolution. They allow improving the quality of these responses. These factors can be found in the data treatment software of an instrument, where often only the default settings are used by the analyst. [Pg.191]

Wang et al. [34] have introduced a new heated mercury film electrode based on a screen printed carbon substrate. It was used in anodic stripping and exhibited a significantly improved signal-to-noise ratio. A directly heated mercury film electrode for anodic stripping voltammetry has been described by Jasinski [35]. Different factors influencing the quality of analytical determination have been investigated. Renewed mercury electrodes and examples of their various applications have been reviewed in Ref. 36. Lovric and Scholz [37] have discussed the conditions... [Pg.967]

The noise reduction procedure reduces the amplitude of the watermarked signal in smooth regions of the image thus improving visual quality. The procedure performs the following steps ... [Pg.8]
