However, this charge pulse contains switching noise caused by the MOS-FETs. Since the linear image sensor have many Si ICs, this switching noise fluctuates because of nonuniformity in MOSFET characteristics. Therefore an efficient noise reduction technique is required for this sensor (Ozawa et al., 1982 Kaneko et al., 1982), as in the case of Si monolithic MOS image sensors (Ashikawa et al., 1973 Aoki et al., 1980). 

Reduction of combustion-generated noise from high-speed jet flows is the topic discussed in Section 2. Fundamental research and novel noise-reduction techniques are presented. These include detailed experimental and computational studies of jet-plume noise, as well as precise measurements. A narrow-band acoustic database generated from actual aircraft landing practice is used as a benchmark for the development of the effective noise-suppression technology.

Engineering Controls Measures taken to prevent or minimize hazard exposure through the application of controls such as improved ventilation, noise reduction techniques, chemical substitution, equipment and facility modifications, etc. 

Three noise reduction techniques were applied to determine Pb at low concentration levels. 

It is worth pointing out that reconstruction of spectra using the basis factors in Equation (7.18) is useful for noise reduction. This noise-reduction technique is much better than spectral smoothing, as chemical information contained in original spectra is not lost, if the number of basis factors is appropriately determined.
