Multiple read-out of signals in presence of arbitrary noises Optimum filters

We present a new method for optimizing the multiple read-out technique of the signal charge detected by a CCD with floating gate output amplifier. The procedure consists in calculating the optimum filter with assigned time domain constraints (e.g. arbitrary finite duration), and in the presence of any kind of uncorrelated, stationary, additional noises. The method is fully developed and applied in practical designing conditions. It can be easily translated into a computer software, which can be used as a tool for optimizing a digital signal processing set-up in its digital filter section.
