In situ quantitation The fluorimetric analysis was made in UV light (2e,c = 313 nm, /-n > 460 nm FI 46 filter). The signal-noise ratio was better above 2 = 460 nm than when a FI 39 filter is employed. [Pg.161]

These techniques offer even more interesting noise-filtering properties as they are capable of localizing time- and frequency-varying noise and signal components. [Pg.23]

The rest of the detector signal is noise filtered and amplified by a lock-in amplifier. The output of the lock-in amplifier is monitored by an oscilloscope, and recorded as the laser scans across the gas s absorption line. The result is a spectral profile of the gas absorption, impressed on the depth of the locked resonance dip. This is then analyzed using (5.6) to find an experimental effective absorption path length. [Pg.106]

Wayman and Wilson, 1988] Wayman, J. and Wilson, D. (1988). Some improvements on the synchronized-overlap-add method of time scale modification for use in realtime speech compression and noise filtering. IEEE Trans. Acoust., Speech, Signal Processing, 36(1) 139-140. [Pg.282]

It also specifies the level of signal that is observed. d This specifies the frequency response of the system and is accompanied by a time requirement. More noise filtering requires a long measurement. e Most commercial burners do not use a sheath gas however, there is always the possibility of a sheath gas in EAAS. f This is important if the sample solution flow rate is controlled by a pump rather than by the oxidant gas flow rate. [Pg.510]

FIGURE 3.10 Use of an exponential filter to improve signal/noise ratio, (a) Acquisition time T = 4T2, with no filter. (6) T = 4T2, with a matched filter, showing better S/N but a broader line. (c) Relative S/N as a function of acquisition time and without a matched filter. [Pg.73]
