Signal processing by counters and digital processing of LDA signals
Abstract
Counter processors play more and more a dominant role among the instruments for LDA data acquisition. A description is given of both dual and single counter systems. Statistical errors caused by the limited number of individual realizations in counter systems are discussed and problems of statistical bias are pointed out. A particular equipment for data acquisition, processing, and data reduction serves as an example for the high efficiency attainable with counter processors.
