P. Lago et al., A MULTIPLE-INPUT DIGITAL CORRELATOR FOR THE WEAK LIGHT-SCATTERING SIGNALS OF CHROMATOGRAPHIC DETECTORS, Review of scientific instruments, 65(1), 1994, pp. 263-264
A simple digital correlator with four independent inputs is described.
It gives 20 correlation points for each channel, with a maximum sampl
ing frequency of 1 MHz, and is fully computer controlled. The correlat
or is designed to match the requirements of dynamic light scattering d
etectors in liquid chromatography.
